Problem 193P
Steam enters a diffuser steadily at 0.5 MPa, 300°C, and 122 m/s at a rate of 3.5 kg/s. The inlet area of the diffuser is
(a) 15 cm2
(b) 50 cm2
(c) 105 cm2
(d) 150cm2
(e) 190 cm2
ANSWER:
Step by step solution Step 1 of 2Steam is entering through a diffuser where the temperature and pressure is specified atdiffuser inlet.We use steady state steady flow analysis for this problem.Thermal properties of diffuser are assumed to be constant.Obtain steam properties that is enthalpy and entropy at different temperatures andpressures are from the linear interpolation of steam data at steam table.Potential energy change is negligible as compared to the changes of kinetic energy.We take the help of control volume analysis for this problem considering that mass iscrossing the boundary of the system and is interacting with the surrounding.\n
