visual studio 2017 c++ 4) The work produced by a piston-cylinder device depends on the pressure inside the cylinder and the amount the piston moves, resulting in a change in volume inside the cylinder. Mathematically In order to integrate this equation, we need to understand how the pressure changes with the volume. We can model most combustion gases as air and assume that they follow the ideal gas law PV- nRT where P- pressure, kPa, volume, m n- number of...
Two mole of ideal gas, is compressed adiabatically in a piston/cylinder device from 2 bar and 25oC to 7 bar. The process is irreversible and requires 25% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas? Assume Cv=(5/2)R in this calculation.
An insulated piston-cylinder device contains 0.1m3 of air (ideal gas) at 400 kPa and 25℃. A paddle wheel within the cylinder is rotated until 15 kJ of work is done on the air while the pressure is held constant. Assuming the kinetic and potential energies are negligible and the gas constant and specific heat of air are ? = 0.287 kJ kg∙K and ?? = 1.005 kJ kg∙K . Tasks: ( a ) Determine the mass of air inside the...
Solution to this please I have an important homework 4) A compressed gas cylinder contains 1.00x10 g of argon gas. The pressure inside the cylinder is 2050. psi (pounds per squared inch) at a temperature of 18°C. How much gas remains in the cylinder if the pressure is decreased to 650. psi at a temperature of 26°C
* A gas is contained in a vertical, frictionless piston-cylinder device. The piston has a mass of 2 kg and a cross-sectional area of 30 cm2. A spring above the piston is compressed by 2.5 mm and has a spring constant, k, of 38 kN/m. a. If the atmospheric pressure is 1 atm, determine the initial pressure (P1) inside the cylinder. Heat is added to the system until the piston moves an additional 10 mm. b. How much did the...
