Q1- A boiler operates at steady state. The entering water is saturated liquid at P = 0.5 MPa and has a flow rate of 2.78 kg/s. The exiting steam is also at P = 0.5 MPa and has 7=400°C. The pipe entering the boiler is 0.08m in diameter, and the pipe leaving the boiler is 0.3m in diameter. What is the rate at which heat is added in the boiler?
