Question

To what head of air (R=287 j/kg K) at an absolute pressure of 101.3kPa and temperature of 15 deg C is a pressure of 75 mm of water equivalent?

Answer 1

Solution: (a) For air, take k 1.40, R 287 J/kg K, and c. p. 1005 J/kg K. ... c T V 518(260) (75) 518(207) V , solve . 2 2 2. Ans ... Use two approaches: (a) an ideal gas from Table A.4;. and (b) real steam from EES or the steam tables [15]. .... At section D, the pressure is 28.2 kPa and the temperature. is –19 C.

(hope this is the solution and sorry if it is wrong because  this is what i understand )
