A steam boiler heats liquid water at 200°C to superheated steam at 4 MPa and 400°C. Methane fuel (CH4) is burned at atmospheric pressure with 50% excess air. The fuel and air enter the boiler at 25°C and the products of combustion leave at 227°C. For T0 = 25°C, find: (a) the amount of steam generated per unit of fuel mass burned, and (b) the specific entropy generation of the combustion
