Answer to Question #219449 in Molecular Physics | Thermodynamics for Ray

Question

A nozzle is a device that is used to accelerate a flowing fluid to higher velocity. If steam flows through an adiabatic nozzle at a steady state entering the nozzle with a pressure of 0.6 Mpa a velocity of 30 m/s and tempreture

Answer 1

$\frac{pv^2}T=const,$

$\frac{p_1v_1^2}{T_1}=\frac{p_2v^2_2}{T_2},$

$v_2=v_1\sqrt{\frac{p_1T_2}{p_2T_1}}=30\cdot\sqrt{\frac{0.6\cdot 623}{0.2\cdot 673}}=50~\frac ms.$
