1. Steam exits a throttle valve at 0.10 MPa and 150C. The pressure at the throttle entrance is known to be 1.75 MPa and the steam to be a mixture of saturated vapor and liquid. (a) What is the temperature at the throttle entrance? (b) What is the quality of the steam at the entrance? (c) Calculate the specific entropy and specific internal energy at the throttle entrance. (d) What is the different between the molar volume of the liquid and the molar volume of the vapor at the throttle entrance
