Problem No: 4 A steam line (0.6 MPa and 200 C) is connected to a rigid evacuated tank immersed in a constant temperature oil bath kept at 200 C. The valve between line and the tank is opened, steam rushes into the tank until its pressure equals that of line. Find the amount of heat transferred from tank to bath or the other way per kg of steam entering the tank. Steam line 0.6 MPa, 200 C Oil bath, 200C Initially evacuated
