Question

Steam flows through a pipe at the rate of 5kg/s. The pressure nd temperature are 12 bar nd 300 degree celsius respectively . If 2000J of heat is lost to the surrounding at constant pressure . Find the final condition of the steam.

Answer 1

If 2000J is the heat lost per second, then Q = νc_p(T₁ – T₂), respectively T₂ = T₁ – Qμ/4Rm = 573 – 36/(4*8.31*5) = 572.8 (K).
