Review: Problem Solving in Isothermal Process 02

During a reversible process there are abstracted 321 kJ/s from 1.234 kg/s of a certain gas while the temperature remains constant at 29.67°C. For this gas, Cp = 2.232 and Cv = 1.713 kJ/kg.°K. The initial pressure is 687 kPa.

Review: Problem Solving in Isothermal Process 02

Problem Statement:

During a reversible process there are abstracted 321 kJ/s from 1.234 kg/s of a certain gas while the temperature remains constant at 29.67°C. For this gas, Cp = 2.232 and Cv = 1.713 kJ/kg.°K. The initial pressure is 687 kPa. For both nonflow and steady flow (ΔP = 0, ΔK = 0) process. Determine (a) v1, v2 and P2 (b) the work and (c) ΔS and ΔH.

Course: Thermodynamics

TOPIC: Processes of Ideal Gas

SUBTOPIC: Isothermal Process

DEFINITION: An Isothermal Process is an internally reversible constant temperature process of a substance.
