Solve The Following Engineering Problem Using Python Code:
Ques 1) The specifi c heat of superheated steam at approximately 150 kPa can be determined
by the equation
Cp=2. 07 + (T-400)/1480 kJ/kg C
(a) What is the enthalpy change between 300 and 700°C for 3 kg of steam?
Compare with the steam tables.
(b) What is the average value of Cp between 300 and 700°C based on the
equation and based on the tabulated data?
Ques 2) Determine the enthalpy change for 1 kg of nitrogen which is heated from 300 to
1200 K by (a) using the gas tables, and (b) assuming constant specific heat.
Use M = 28 kg/kmol.
