Solved Problems for ISOTHERMAL Process | Discussion of Formulas | Step by Step Solution

Описание

An isothermal process is a thermodynamic process, in which the temperature of the system remains constant (T = C) and therefore ΔT =0.
Sample Problems in this video include:
1. If 10 kg/min of air are compressed isothermally from P1 = 96 kPa and V1 = 7.65 m3/min to P2 = 620 kPa, find the work, change of entropy and heat for
A) nonflow process
B) a steady flow process with v1 = 15 m/s and v2 = 60 m/s
2. Nitrogen at an initial state of 300 K, 150 kPa, and 0.2 m3 is compressed slowly in an isothermal process to a final pressure of 800 kPa. Determine the work done during this process.
3. A piston–cylinder device initially contains 0.4 kg of nitrogen gas at 160 kPa and 140 deg C. The nitrogen is now expanded isothermally to a pressure of 100 kPa. Determine the boundary work done during this process.
