The stators in a gas turbine are designed to increase the kinetic energy of the gas passing through them adiabatically. Air enters a set of these nozzles at 300 psia and 700°F with a velocity of 82 ft/s and exits at 250 psia and 645°F. Calculate the velocity at the exit of the nozzles. The specific heat of air at the average temperature of 672.5°F is cp = 0.253 Btu/lbm·R.

Given Information:

Inlet Temperature = T₁ = 700° F

Exit Temperature = T₂ = 645° F

Inlet Velocity = v₁ = 82 ft/s

Specific heat of air = cp = 0.253 Btu/lbm.R

Required Information:

Exit velocity = v₂ = ?

Exit velocity =  

Explanation:

As we know the energy balance equation is given by

1 Btu/lbm is equal to 25037 ft²/s²

explanation:

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
