Air contained in a piston-cylinder undergoes two processes in series. In the first the air expands according top V = C from 300 kPa and a specific volume of 0.021 m 3 /kg to a pressure of 140 kPa. The second process is a constant pressure compression until specific volume 3 equals specific volume 1. Sketch the processes on a p- V diagram and determine the work per unit mass.
A sketch of set of four processes involved in a closed thermodynamic system is shown in the adjoining pressure- volume diagram. Isothermal expansion brings 220 grams of a fluid from 415 kPa to a final pressure of 115 kPa and specific volume of 120 litres/kilogram. A reversible cooling process takes place at constant pressure with a work done of 525 Joules and then followed by a constant volume until the pressure of the fluid becomes 62 kPa. A Polytropic compression...
PROBLEM 1Air undergoes two processes in series:Process 1-2: Polytropic compression, with n = 1.3, from p1 = 110 kPa, V1 = 0.5 m3 to V2 = .1 m3Process 2-3: Constant pressure process to V3 = V1Determine the work done in each process and comment on the direction of work. Then, determine the net work from Process 1 - 3. (You may assume air to behave as ideal gas throughout process)PROBLEM 2 Air is compressed isothermally in a piston cylinder. If the initial...
Problem 7 A system undergoes a thermodynamic cycle consisting of four processes in series. The table below provides some data, where the familiar sign convention for first-law analysis is adopted. The system is a closed system. Kinetic energy and potential energy effects can be neglected. a. Using first-law analysis and the energy balance for a cycle, find the missing values in the table. b. Determine whether the cycle is a power cycle or refrigeration cycle. c.Show that the net amount...
