Chapter 6, Problem 6.18P

Question A tank of 2m3 volume contains Saturated ammonia at a temperature of 40 ° c, the tank.contains 50% liquid and 50% vapor by volume. Find the Specific volume, enthalpy and intenal energy of the mixture.

With 3% moisture, 2.5 kg of steam has an enthalpy of 6600 kJ. It is heated at constant pressure to a final condition of 80 o Find (a) the pressure of the process, (b) the quantity of heat received by the steam, and (c) draw and use h-s diagram.

Can you solve this problem (full solution) for my thermodynamics subject. Thank you 4. Five kg of water vapor are contained at 150 kPa and 90 percent quality in a suitable enclosure. Calculate the heat which must be added in order to just produce a saturated vapor. What will the pressure be at the end of the heating process?     Ans. 1045.5 kJ, 168 kPa.
