Three return steam lines in a chemical processing plant enter a collection tank operating at steady state at 5 bar. Steam enters inlet 1 with flow rate of 2 kg/s and quality of 0.9. Steam enters inlet 2 with flow rate of 2 kg/s at 200°C. Steam enters inlet 3 with flow rate of 1.2 kg/s at 95°C. Steam exits the tank at 5 bar. The rate of heat transfer from the collection tank is 40 kW. Neglecting kinetic and potential energy effects, determine for the steam exiting the tank:
(a) the mass flow rate, in kg/s.
(b) the temperature, in °C.

Annealing is a process by which steel is reheated and then cooled to make it less brittle. Consider the reheat stage for a 100-mm-thick steel plate (ρ= 7830 kg/m3, c= 550 J/kg·K, k= 48 W/m·K), which is initially at a uniform temperature of Ti= 120°C and is to be heated to a minimum temperature of 550°C. Heating is effected in a gas-fired furnace, where products of combustion at ∞T∞= 800°C maintain a convection coefficient of h=250 W/m2·K on both surfaces of the plate. How long should the plate be left in the furnace?
