//DATA GIVEN
m=4.4; //mass of steam to be produced in kg
p=6; //pressure of steam
Tsup=250; //temp. of steam in deg. celsius
Tw=30; //temp. of water in deg celsius
Cps=2.2; //specific heat of steam in kJ/kg
//At 6 bar, from steam tables
Ts=158.8; //deg. celsius
hf=670.4; //kJ/kg
hfg=2085; //kJ/kg
//since the given temp. 250 deg celsius is greater than 158.8 deg celsius, steam is superheated
hsup=hf+hfg+Cps*(Tsup-Ts); //enthalpy of 1 kg supergeated steam reckoned from 0 deg. celsius
hs=1*4.18*(Tw-0); //sensible heat associated with i kg of water
hnet=hsup-hs; //net quantity of heat to be supplied per kg of water
Htotal=m*hnet; //total amount of heat to be supplied
