Water enters a boiler tube at 50 deg-C, 10 MPa at a rate of 10 kg/s. Heat is transferred from the hot surroundings in the boiler (created by combustion of coal) maintained at 1000 deg-C. Water exits the boiler as saturated vapor. Determine
(a) The heating rate in MW.
(b) The rate at which entropy is generated in the boiler tube's universe in kW/K. Assume steady state. Neglect any pressure drop in the boiler, and changes in ke and pe.
