The gas mixture formed as a result of the combustion of the stoichiometric mixture consisting of methane (CH4) and humid air reaches a temperature of 1500 K and a pressure of 80 bar. In this case, calculate the specific entropy value of the products on a molar and mass basis. Take the specific humidity of the humid air as 0.01 kg sb/kg Hk.
Determine the entropy change of 1.5 moles of ammonia that is heated from 180°C to 750°C. The system operates at an atmospheric pressure on a steady flow process.
The volumetric analysis of a mixture of gases is 35 percent ethylene and 65 percent ethane.This mixture is heated from 175◦C to 335◦C while flowing at a rate of 0.28 kg/s through a heat exchanger in which pressure is maintained at 270 kPa. Determine the rate of heat transfer to the mixture.
