Thermal Engineering MCQs: 540 Questions & Answers in Engineering

For water, at pressures below atmospheric,

At very low temperature, the melting and boiling temperatures become equal. This temperature is

The critical pressure at which latent heat of vaporisation is zero is

The latent heat of steam at pressures greater than atmospheric in comparison to latent heat at atmospheric pressure is

The saturation temperature of steam with increase in pressure increases

Heating of dry steam above saturation temperature is known as

Superheating of steam is done at

Sublimation region is the region where

One kg of steam sample contains 0.8 kg dry steam; it's dryness fraction is

If a steam sample is nearly in dry condition, then its dryness fraction can be most accurately determined by

On Mollier chart, flow through turbine is represented by

A wet vapour can be completely specified by

On Millier chart, the constant pressure lines

The dry saturated steam at very low pressure, (5-10 kg/cm2) when throttled to atmosphere will become

On Mollier chart, free expansion, or throttling process from high pressure to atmosphere is represented by

In a throttling process

The dry saturated steam at very high pressure (150-200 kg/cm2) when throttled to atmosphere will become

The latent heat of steam with increase of pressure

In a throttling process

In an experiment to determine dryness fraction of steam, the mass of water separated was 1.2 kg in 15 minutes and the mass of steam passed out in same time was 4.8 kg. Dryness fraction is
