- A gas flows steadily through a rotary compressor at a temperature of 16 ⁰C, a pressure of 100kPa, and an enthalpy of 392.2 kJkg-1. The gas leaves the compressor at a temperature of 245⁰C, a pressure of 0.6 MPa and an enthalpy of 534.5 kJkg-1. There is no heat transfer to or fromthe gas as it flows through the compressor. Using the steady flow equation appropriate toeach case, evaluate the external work done per unit mass of gas: a) when the inlet and exit velocities of the gas are negligible b) when the inlet velocity of the gas is 80 ms-1 and the exit velocity of the gas is 160 ms-1.What are the basic parameters for calculating of Jet Pulse Compress Air for cleaning of bags from dust in Bag Filters and Bag Houses?Ex: A combustion chamber consists of tubular combustors of 15-cm diameter.
