Solution:

What is the typical gap range between the electrodes of spark plugs in automobiles?

0.6 to 1.8 mm

0.2 to 0.8 mm

0.4 to 0.9 mm

0.3 to 0.7 mm

Solution:

Find the reverse Carnot coefficient of performance (COP) if the condenser and evaporator temperatures are 220 K and 100 K respectively.

1.2

1.4

2.4

2.2

Solution:

The load on the condenser is given by the formula (where Q_c = Load on the condenser; R_c = Refrigeration capacity)

Qc = Rc / W

Qc = Rc + W

Qc = Rc - W

Qc = Rc * W

Solution:

As refrigerant moves through the condenser, it goes from _ to _.

a Vapor to Liquid

a Liquid to Vapor

Low-pressure Vapor to a low-pressure vapor

High-pressure liquid to a low-pressure liquid

Solution:

Which of the following refrigeration systems is most suitable for solar cooling?

Ejector refrigeration system

Vapour absorption system

Desiccant refrigeration system

Vortex tube refrigeration system

Solution:

If the reverse Carnot coefficient of performance (COP) is 2.6, and the condenser and evaporator temperatures are 'X' K and 110 K respectively, then find the value of 'X'.

397 Kelvin

297 Kelvin

387 Kelvin

392 Kelvin

Solution:

In a domestic icebox type refrigerator, the ice block is kept at the top because

disposal of water is easier

hot air can be easily removed from the top

cold air can flow down due to buoyancy effect

it is easy for the user to operate
