Steam with a mass flow rate of 3 kg/s at 400C and 3 MPa (stream 1) is throttled to a pressure of 300 kPa (stream 2). Stream 2 is then mixed with saturated liquid water at 300 kPa with a mass flow rate of 7 kg/s (stream 3). Determine the temperature of the stream 4 leaving the mixing chamber at 300 kPa. Assuming the mixing chamber is fully insulated. Stream 3 Saturated Liquid Water 7 kg/s, 300 kPa Stream 2 300 kPa Stream 1 Steam 3 kg/s, 400C, 3 MPa Mixing Chamber Stream 4 300 kPa Select one: Correct Answer 4 a. 133.52C Cross out
