What is the code for 'or' in the code language Statements : I. 'nik sa te' means 'right or wrong', 'ro da nik' means 'he is right' and 'fe te ro' means 'that is wrong'. II. 'pa nik la' means 'that right man', 'sa ne pa' means 'this or that' and 'ne ka re' means 'tell this there'.?
Answer: Option 3 I. In 'right or wrong' and 'he is right', the common word is 'right' and the common code word is 'nik'. So 'nik' means 'right'. In 'right...

Wet bulb temperature is the temperature of air recorded by a thermometer, when?
Answer: Option 2 Wet-bulb temperature. The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed. At 100% relative...

The bypass factor (B. P. F.) in case of sensible heating of air is (Where td₁ = Dry bulb temperature of air entering the heating coil, td₂ = Dry bulb temperature of air leaving the heating coil, and td₃ = Dry bulb temperature of heating coil)?
Answer: Option 2 The bypass factor (B. P. F.) in case of sensible heating of air is (td₃ - td₂)/(td₃ - td₁) Where, td₁ = Dry bulb temperature of air entering the...

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...
