Question

Saturated vapor ammonia (NH3) is heated in a constant volume system from 100 to 180 degrees Fahrenheit. What is the final pressure of the ammonia, in psi? Round to the nearest integerplease show all interpolations and use english tabel because final answer is in psi.

Thank you very much!

Answer #1

Hey, in case of any doubt feel free to drop me a comment.

Given data: T1 100°F, T2 180°F. Constant-Volume System hence, (-91 92) Initial State: From, Table - A13E at [T1 100°F] 8-81-2- 1.4168 ft/lb] Final State: As, Ammonia was at Saturated Vapor state initially and once, we heat it even more it will go into a Superheated state hence, From, Table -A15E at [T2 180°F, 1.4168 ft3/lb] (This specific volume lies between the Pressures of P1-250 lbf/in2 and P2 300 lbf/in2) hence, to find final Pressure (PFinal) we will interpolatate the corresponding values of Pressures and Specific volumes. P 250 lbf/in2, P2 300 lbf/in2 81-1.4539 ft3/lb, Э2-1.1822 ft3/lb 9 1.4168 ft3/Ib Formula for Linear interpolation: Pinal [P1+((2- (P2- P) PFinal [250 (1.4168-1.4539) (1.1822 - 1.4539) (300 250) Prinal 256.83 lbf/in2 or 256.83 Psi...
