A rigid tank contains 10 kg of water. . It can be safely assumed that the pressure increase from 100kPa to 200kPa is linear with respect to volume. Justify that Cp specific heat at constant pressure is always greater than Cv specific heat at constant volume for an ideal gas in a freely moveable piston cylinder system? Find internal energy of compressed liquid water using: i. Write down energy balance equation for cyclic system.

How is low temperature achieved in vacuum cooling process? Cancel the membership at any time if not satisfied. Determine the missing properties and the phase descriptions in the following table.
You just select your branch from be , bpharm , mba , mca , dpharm , mpharm , pddc , me and diploma and your sem of sem1 , sem 2 , sem3 , sem 4 , sem 5 , sem 6 , sem 7 , sem 8. The piston has an area of 1m2. Air at 100 psi and 300°F is contained in a rigid iron cylinder. Note: We cannot guarantee that every book is in the library. In the first stage, the products at ambient temperature are loaded into the chamber, whose temperature is kept constant until saturation pressure is reached. Temperature and pressure inside the cylinder drops to 150°F and 60 psi respectively as a result of heat transfer to surrounding.
In the second stage, saturation conditions are maintained at lower pressures and the corresponding lower temperatures until the desired temperature is reached. For all of the following cases take initial volume and pressure of the fluid as 1m3 and 100kPa respectively. Saturated Liquid data How much error % exists between the two results? Find out the work done by air during such heat transfer process. After neglecting mass, only heat Q and work W will left. Final volume of the fluid is 2m3. Define Latent Heat of Fusion? A working fluid is contained in a piston-cylinder system. Whichever your branch is, like bachelor of engineering B.
Also, draw a T-u diagram showing magnitude of stated properties. We hope you glad to visit our website. This extra amount of heat is never required in piston cylinder device having fixed volume as no boundary work is involved. The heat of vaporization during evaporation is absorbed from the products, which lowers the product temperature. Solution Since the tank is rigid, so there is no change in volume.
You might have gone to other sites on the internet along with the official gtu site i. Find the work done if: a 10J energy is added to the system following an isochoric process. As volume increases temperature tends to decrease so extra amount of heat is required to accommodate this tendency in the drop of temperature which results in the form of boundary work. What is meant by specific heat of a gas? Register a free 1 month Trial Account.
