San Francisco State University ENGR 303: Engineering Thermodynamics School of Engineering Prof. Ed Cheng, Spring 2011 Homework 2 solutions NOTE : Solutions for HW problems that are based upon textbook problems reflect numerical values from the text. Numerical values may differ for these problems when they appear on iLearn. In such cases, the solution presented below provides the appropriate solution method . 1. The correct answer is (b). Pressure and temperature are not independent when a substance is in a saturated state. I.e. , there is a one-to-one relationship between saturation pressure and temperature. 2. The correct answer is (a). One way of understanding this is to consider a P-V diagram. Slightly increasing the pressure at constant temperature forces the state left and up relative to the saturated liquid line ( i.e. , into the compressed liquid region).

Unformatted text preview: 3. The correct answer is (d). One way of understanding this is to consider a T-V diagram. Slightly increasing the temperature at constant pressure forces the state right and up relative to the saturated vapor line ( i.e. , into the superheated vapor region). Missing values are given above, although specific solution procedures not provided. Please review in-class example regarding obtaining properties from tables. See Prof. Cheng if you are having difficulty in understanding how the above values are determined. 4-8: San Francisco State University ENGR 303: Engineering Thermodynamics School of Engineering Prof. Ed Cheng, Spring 2011 HW 2 solutions 2 9: San Francisco State University ENGR 303: Engineering Thermodynamics School of Engineering Prof. Ed Cheng, Spring 2011 HW 2 solutions 3 10-11:...
