Extracted text: A. Two kg of steam with a quality of 22 percent is heated at a constant pressure of 300 kPa until the temperature reaches 500°C. Calculate the work done by the steam. B. A 5-hp fan is used in a large room to provide for air circulation. Assuming a well-insulated, sealed room determine the internal energy increase after 1 h of operation.
