Nozzles, Diffusers

A nozzle receives an ideal gas flow with a velocity of 25 m/s, and the exit at 100 kPa, 300 K velocity is 250 m/s. Determine the inlet temperature if the gas is argon, helium, or nitrogen.

Solution 21 HP

Step 1 of 5</p>

We need to find the inlet temperatures of Argon, Helium and Nitrogen

Step 2 of 5</p>

Energy equation is given by

J/kg

kJ/kg

Step 3 of 5</p>

We get specific heats of ideal gases from table A.5

kJ/kg.K for argon

Use the formula to find inlet temperature

K

Inlet temperature of Argon gas is K
