The water leaves the boiler tube at 50 bar and 700oK at velocity of 100m/s. Calculate the inlet volume flow(li/sec). SOLUTION From steam tables: At 70bar(7MPa) and 65oC v1 = 0.001017m3/kg at 50bar(5MPa) and 700oK(427oC) v2 = 0.06081m3/kg m1 = m2 Q1/ v1 = Q2/ v2 V1 = 1.672m/sec Q1 = A x v = (π/4)(0.035)2(1.672) = ANS.Read More
