Air flows at steady state through a horizontal, insulated pipe with inside diameter of 4 cm. A pressure drop results from flow through a partially opened valve. Just upstream from the valve, the pressure is 7 bar, the temperature is 45°C, and the average velocity is 20 
If the pressure just downstream from the valve is 1.3 bar, what is the temperature? Assume for air that PV/T is constant, 
= (5/2)R, and 
= (7/2)R.
