Question

Nitrogen flows at steady state through a horizontal, insulated pipe with inside diameter of 38.1 mm. A pressure drop results from flow through a partially opened valve. Just upstream from the valve the pressure is 690kPa, the temperature is 322.15 K (49"C), and the average velocity is 6.09 m/s. If the pressure just downstream from the valve is 138 kPa, what is the
