The sensible heat factor during the heating and humidification process is given by (where h₁ = Enthalpy of air entering the heating coil, h₂ = Enthalpy of air leaving the heating coil, and hA = Enthalpy of air at the end of humidification process)?

Answer: Option 4 The sensible heat factor during the heating and humidification process is given by (hA - h1)/ (h2 - h1)

The compressibility factor of a gas is given by (where, V₁ = actual volume of the gas V₂ = gas volume predicted by ideal gas law )?

Answer: Option 1 The compressibility factor is given by $$Z = \frac{{P{V_1}}}{{RT}}.$$   If at the same temperature and pressure if the same gas exists as ideal gas than we...

Directions : Each of the following question consists of a statement followed by two arguments I and II. You have to decide which of the arguments is a STRONG arguments and which is a WEAK Argument. Statement : Should the practice of transfers of clerical cadre employees from government offices of one city to those of another be stopped Arguments : I. No. Transfer of employees is a routine administrative matter and we must continue it. II. Yes. It involves lot of governmental expenditure and inconvenience too many compared to the benefits it yields.?

Answer: Option 4 It is not necessary that any practice which has been in vogue for a long time is right and it must be continued. So, argument I is...
