Work done on a body is not only the displacement of the body as a whole from one place to another but also the displacement of particles in the body. For example, rotation of a shaft, compression of a gas, and even motion of internal particles caused by an externalmagnetic fieldcount as...
aEvaporative condensers pass outdoor air over coils sprayed with water, thus taking advantage of adiabatic saturation to lower the condensing temperature. 蒸发冷凝器通过用水盆射的室外空气卷,因而利用绝热饱和降低凝聚的温度。 [translate] ametallkraft presentation metallkraft介绍 [translate] a截止到2003年 ...
work equation for an isothermal process Isothermal Process: The temperature T is kept constant during the whole process:W= integral Vf to Vi (PdV)= integral Vf to Vi (nRT/V) dV= nRT (integral Vf to Vi ( (1/V)dV) = nRT ln(Vf/Vi) work equation for an adiabatic process Adiabatic Pr...
Based on the concept of identical processes, numerical simulations of adiabatic irreversible compression and expansion were performed, enabling a better understanding of differences between configuration and dissipative work. The positive nature of the dissipative work was used to discuss the case where ...
Carbon dioxide enters an adiabatic nozzle steadily at 1 MPa and 500 C with a mass flow rate of 6000 kg/h and leaves at 100 kPa and 450 m/s. The inlet area of the nozzle is 40 cm . Determine (a) the What is the pressure conversion factor for torr to kPa? The lowest p...
Any small patch on the surface of the container of gas experiences a force due to the pressure exerted by the gas. During the expansion or compression of a gas, the walls of the container of the gas are displaced...
Work done for an isothermal compression is W=−vRTlnV2V1 but I have no information about the temperatur or number of mols. Can anyone guide me in the right direction? The answer is 780 kJ but I can't get there. Physics news on Phys.org Benchmarking the Continuous Electron Beam ...

No heat transfer =Adiabatic Process A process during which there is no heat transfer is called an adiabatic process. The adiabatic process should not be mixed with Isothermal process. A process could be an adiabatic process while the temperature of a system is changing . 7 ...
