A ridged container was charged with 6.0 lbm of ammonia. Initially the ammonia was at 20 F and had a quality of 36%. After the container was sealed shut, heat was allowed to transfer slowly into the container. Please determine i. The initial pressure in psia. ii. The temperature and pressure at which the system first attains a quality of 100%. iii. How much heat (in Btu) must be transferred to increase the temperature to 30 F? Solution Extend the time and I can answer the question for you with complete work.
