Engineering Thermodynamics A process, in which the gas is heated or expanded in such a way that the product of its pressure and volume remains constant, is called Adiabatic process Hyperbolic process Polytropic process Isothermal process Adiabatic process Hyperbolic process Polytropic process Isothermal process ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics Work-done during adiabatic expansion is given by (where p1 v1, T1 = Pressure, volume and temperature for the initial condition of gas, p2, v2, T2 = Corresponding values for the final condition of gas, R = Gas constant, and γ = Ratio of specific heats) [m R T1/(γ - 1)][1 - (p2, v2 /p1 v1)] [m R (T1 - T2)] /(γ - 1) All of these (p1 v1 - p2, v2)/(γ - 1) [m R T1/(γ - 1)][1 - (p2, v2 /p1 v1)] [m R (T1 - T2)] /(γ - 1) All of these (p1 v1 - p2, v2)/(γ - 1) ANSWER DOWNLOAD EXAMIANS APP
