Problem 2 A diffuser is a device designed to decrease the velocity of a steadily flowing stream while increasing its pressure. At the inlet to a certain diffuser, the enthalpy of the fluid is 276 kJ/kg and the velocity is 250 m/s. At the discharge end, the enthalpy is 300 kJ/kg.

Transcribed Image Text:Problem 2
A diffuser is a device designed to decrease the velocity of a steadily flowing stream while increasing its pressure. At the inlet to a
certain diffuser, the enthalpy of the fluid is 276 kJ/kg and the velocity is 250 m/s. At the discharge end, the enthalpy is 300 kJ/kg.
The diffuser is horizontal and there is zero heat loss from it. (Be careful about units!)
(a) Calculate the velocity at the exit of the diffuser.
(b) If the inlet area is 0.08 m² and the specific volume at the inlet is 0.15 m³/kg, determine the mass flow rate through the diffuser.
du - through
26, 20
(c) If the specific volume at the exit of the diffuser is 0.22 m³/kg, find the diameter of the exit section.
