A carnot engine is made to work on amonoatomic gas first (g = 1.67) and then on adia atomic gas (g = 1.4). Among the two whichwill have better efficiency
Two carnot engine are in series operatingbetween source temperature of 180º C and 20ºCsink temperature. If both produce equal amountof work the intermediated temperature is.
Which law of thermodynamics predicts the degree of completion of chemical reactions.
Isentropic flow is always
1. zero increase in entropy flow.
2. revertrible adiabatic flow.
3. Frictionless reversible flow.
In fluid dynamics, an isentropic flow is a fluid flow that is both adiabatic and reversible. That is, no heat is added to the flow, and no energy transformations occur due to friction or dissipative effects. For an isentropic flow, entropy density can vary between different streamlines.
Joule thomson coefficient is the slope of constantenthalpy lines in

A vessel of volume 1m3 contains oxygen(molecular weight = 32) at P = 1 bar and T = 47º C. The mass of oxygen in vessel is [R = 8314 J/mol-k]
As temperature increases values of Cp, Cv and g for polyatomic gas
The heat transfer in a polytropic process can be given as.
