Engineering Thermodynamics The heat supplied to the gas at constant volume is (where m = Mass of gas, cv = Specific heat at constant volume, cp = Specific heat at constant pressure, T2 - T1 = Rise in temperature, and R = Gas constant) mR (T2 - T1) mcv (T2 - T1) mcp (T2 + T1) mcp (T2 - T1) mR (T2 - T1) mcv (T2 - T1) mcp (T2 + T1) mcp (T2 - T1) ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The distillation carried out in such a way that the liquid with the lowest boiling point is first evaporated and re-condensed, then the liquid with the next higher boiling point is then evaporated and re-condensed, and so on until all the available liquid fuels are separately recovered in the sequence of their boiling points. Such a process is called Fractional distillation Carbonisation Cracking Full distillation Fractional distillation Carbonisation Cracking Full distillation ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics For a perfect gas, according to Boyle’s law (where P = Absolute pressure, V = Volume and T = Absolute temperature) P v = constant, if T is kept constant P/T = constant, if v is kept constant T/P = constant, if v is kept constant V/T = constant, if p is kept constant P v = constant, if T is kept constant P/T = constant, if v is kept constant T/P = constant, if v is kept constant V/T = constant, if p is kept constant ANSWER DOWNLOAD EXAMIANS APP
