Dew point temperature lines on the psychometric chart are

The lowest temperature during the cycle in a vapour compression system occurs after

The principle of vapour compression system is that fluids absorb heat while changing from a

Sensible heat factor is defined as the ratio of

In vapour compression refrigeration system, heatrejected as compared to heat absorbed is

As warm air cools, it’s relative humidity

Consider the shaded triangle region P shown in the figure
What is $$\int\int_{P} xydxdy$$

Distance between origin and_ the point nearest to it on the surface $$z^2 = 1 + xy$$ is:

At $$x = 0$$, the function $$f(x) = \mid x \mid$$ has

General solution of differential equation $$\frac{dy}{dx} = \cos(x + y)$$ is
