  4. Find the current passing through 3 Hp pump motor having 0.8 Power factor connected across 230V. (Unit 4: Hospitality Engineering – Electricity)
    → Solution

We know the formula,

P = V * I * Power factor
where,
P = Power in watts (W)
V = Voltage in volts (V)
I = Current in amperes (A)

Converting horsepower into watts

1 Hp = 746

Using the formula,

P = V * I * Power factor
or, 2238 = 230 * I * 0.8
or, 2238 = 184 I
or, 2238 / 184 = I
∴ I = 12.16A

Thus, the current passing through the 3 HP pump motor is approximately 12.15 A.

    • Beams
    • Walls
    • Lintels
    • Damp Proof Course (DPC)
  2. Mention the type of parking according to service. (Unit 2: Design and planning)
    The type of parking according to service are:
    • Self-parking – Guests park their vehicles themselves in designated spots.
    • Valet parking – A valet attendant parks the vehicles for guests.
    • Automated parking – Mechanical systems or machines park the vehicles automatically.
  3. List down the steps to extinguish fire. (Unit 4: Hospitality Engineering -Safety & Securities)
    → The steps to extinguish fire are:
    • Evaluate the fire – Determine the size and type of fire.
    • Pull the alarm – Notify others and call emergency services.
    • Use the correct fire extinguisher – Choose the extinguisher suited for the class of fire (e.g., water for Class A, CO2 for Class B).
    • Aim at the base of the fire – Direct the extinguisher nozzle at the fire’s base.
    • Sweep the extinguisher – Move the extinguisher side to side to cover the entire area.
    • Evacuate if necessary – If the fire grows or becomes uncontrollable, evacuate immediately.
  4. Define capital project cost. (Unit 3: Hotel Building Economic)
    → Capital project cost refers to the total expenditure required for the construction, renovation, or major maintenance of a building, including expenses related to land acquisition, materials, labor, equipment, design, and permits. It includes all costs necessary to complete and operate the project.
  5. When will short circuits occur in a circuit? (Unit 4: Hospitality Engineering – Electricity)
    → A short circuit occurs when electrical current flows through an unintended path of low resistance, bypassing the normal circuit. This usually happens due to faulty wiring, damaged insulation, or direct contact between live wires, resulting in a surge of current that can cause overheating and potential fire hazards.
  6. How do you explain electromagnetic wave? (Unit 4: Hospitality Engineering – Electricity)
    → Electromagnetic waves are waves of energy that propagate through space, consisting of oscillating electric and magnetic fields. These waves travel at the speed of light and do not require a medium to move through. Examples include light, radio waves, and X-rays.

    Simply, Electromagnetic waves are energy waves made up of electric and magnetic fields that move together
  7. Explain British thermal unit. (Unit 4: Hospitality Engineering – Heat & Light)
    → A British Thermal Unit (BTU) is a unit of measurement for energy. It represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is commonly used in heating and cooling systems to measure energy consumption or output.
  8. Enlist two properties of good Refrigeration. (Unit 5 : Food Service Refrigeration)
    → Any two properties of good refrigeration are:
    • Low boiling point – Ensures efficient heat absorption and cooling.
    • Non-toxic and non-flammable – Ensures safety for use in refrigeration systems.
  9. Write down the full form of CCTV. (Unit 4: Hospitality Engineering -Safety & Securities)
    → The full form of CCTV is ‘Closed Circuit Television’.
  10. Define coefficient of performance. (Unit 5 : Food Service Refrigeration)
    → Repeated question from 2019, Qn No. 9 (Please refer back to that year)
  11. A refrigerator extracts heat from foodstuffs at a capacity of 1.5 ton of refrigeration. The electric motor driving the compressor of the refrigeration unit consumes-power of 1.2 kw. Determine the COP of the unit. (Unit 5 : Food Service Refrigeration)
    → Solution

We know,
1 ton of refrigeration is equivalent to 3.517 kW.

Given,
Cooling capacity = 1.5 ton
= 1.5 * 3.517
= 5.2755 kW
Power input = 1.2kw

Now,

COP = Cooling Capacity / Power Input

COP = 5.2755 / 1.2
=4.39625

Therefore, Coefficient of Performance (COP) of the refrigeration unit is approximately 4.40.

  1. Explain in brief about different types of fire extinguishers. (Unit 4: Hospitality Engineering – Safety & Securities)
    → Each extinguisher is designed for specific types of fires, so it’s important to use the right one for the situation. The different types of fire extinguishers are:
    • Water Extinguishers (Class A): They are used for fires involving solid materials like wood, paper, and fabric. They work by cooling the fire and removing the heat.
    • Foam Extinguishers (Class A & B): They are effective for fires involving flammable liquids like petrol and oils, as well as solid materials. Foam creates a barrier between the fire and the oxygen, smothering it.
    • Dry Powder Extinguishers (Class A, B, C): They are suitable for fires caused by flammable gases, liquids, and electrical equipment. It works by smothering the fire, removing oxygen.
    • Carbon Dioxide (CO2) Extinguishers (Class B & Electrical): They are used for electrical fires and flammable liquid fires. CO2 extinguishers work by displacing oxygen and cooling the fire.
    • Wet Chemical Extinguishers (Class F): They are designed for kitchen fires involving oils and fats, like deep-fat fryers. They cool and smother the fire, preventing it from re-igniting.
  2. Define protecting device. Explain why protecting device is necessary in circuit. How fuse is differing from Miniature Circuit Breaker? (Unit 4: Hospitality Engineering -Safety & Securities and Electricity)
    → A protecting device is an electrical component designed to safeguard electrical circuits and equipment from damage due to faults, overloads, or other abnormal conditions. These devices interrupt the flow of electricity when a fault is detected, preventing potential damage and ensuring safety.

    Protecting device is necessary in circuit because:
    • Prevent Damage: Avoids damage to circuits and equipment.
    • Enhance Safety: Reduces risk of electrical fires and shocks.
    • Minimize Downtime: Limits disruption to only affected areas.
    • Compliance: Ensures adherence to safety standards.
    • Prevent Overloading: Stops circuits from overheating.

The difference between fuse and Miniature Circuit Breaker (MCB) are:

BasisFuseMCB
Operation Melts and breaks the circuit when excessive current flows.Automatically switches off and disconnects the circuit when an overload or short circuit occurs.
ResettingRequires replacement of the fuse element once it blows.Can be reset manually by switching it back on after it trips.
Response timeGenerally slower in response compared to MCBs.Responds quickly to overloads and short circuits.
IndicatorNo visual indicator when it blows; must be checked.Typically has a visible switch that indicates the tripped status.
CostCheaper than MCBExpensive than fuse, but durable
UseCommon in older installations and simple circuits.Common in modern installations and more complex circuits.

  2. Describe about the maintenance management system of Hotel. (Unit 4: Hospitality Engineering – Maintenance)
  3. Explain the five-safety precaution that must be adopted while using electronic appliances. Suppose a 3-star hotel is using these items: (Unit 4: Hospitality Engineering – Electricity)
    • 1000 number Of 25 watts bulbs for 4 hours and 45 minutes per day
    • 300 units TV Of 200 watts average 12 hours per day
    • Freeze & refrigeration 25 units of 150 watts 24 hours per day
    • 7.5 hp electric pumps 3 hours and 30 minutes per day
    • If electric tariff per KW hr, is Rs 10 per units, Calculate the monthly bill for the month Of July.

→ Solution

Considering, The total days count in July is 31.

We know,
1 hp = 0.746 kW
1 kW = 1000 W

ItemsNumberPower Consumption (kWh)Duration (In hours) Daily Energy Consumption (kWh)Monthly Energy Consumption
Bulb10000.0254 + 0.75 = 4.75118.753681.25
TV3000.21272022320
Freeze & refrigeration250.1524902790
Electric pumps15.6 (7.5 hp ≈ 5.6 kW)3 + 0.5 = 3.519.6607.6
Total949.35 units29,398.85 units
Bill Calculation = 29,398.85 * 10 = Rs. 2,93,988.5

The monthly electricity bill for the month of July is Rs 293,988.50.

Working Note:

Energy Consumption (kWh) = Number of bulbs × Power consumption per bulb × Duration

  • Bulb: Units = 1000 bulbs × 0.025kWh × 4.75hours = 118.75 kWh
  • TV Units=300 TVs × 0.2 kWh × 12 hours = 720 kWh
  • Freeze & Refrigeration: Units = 25 units × 0.15 kWh × 24 hours=90 kWh
  • Electric Pumps: Units = 1 pump × 5.6 kW × 3.5 hours = 19.6 kWh
Total Units = 118.75+720+90+19.6=949.35 kWh
