Relative humidity is given by (where pv = Partial pressure of water vapour, pb = Barometric pressure, ps = Pressure of saturated air, pd = Pressure at dry bulb temperature, pw = Saturation pressure corresponding to wet bulb temperature, and μ = Degree of saturation)?
Answer: Option 2 Relative humidity is given by μ/[1 - (1 - μ) (Ps/Pb)] where pv = Partial pressure of water vapour, pb = Barometric pressure, ps = Pressure of saturated air, pd...

On a P-V diagram of an ideal gas, suppose a reversible adiabatic line intersects a reversible isothermal line at point A. Then at a point A, the slope of the reversible adiabatic line (∂P/∂V)S and the slope of the reversible isothermal line (∂P/∂V)T are related as (where, y = Cp/Cv) )?
Answer: Option 3 For an adiabatic process → $$P{V^y}$$ = constant For an isothermal process → $$PV$$ = constant So, slope for adiabatic process in $$PV$$ plane is $$\frac{{dp}}{{dv}} = - y\frac{p}{v}$$ Slope...

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer : Statement : The State Government has abolished the scheme of providing concessional air ticket to students. Assumptions : I. Students will not travel by air in future. II. The students who resort to travel by air can bear the expenses of air ticket.?
Answer: Option 2 The scheme has been abolished not to discourage the students from travelling by air but keeping in mind that the abolition of scheme won't stop them from...
