Question

Steam flows through a nozzle at a mass flow rate of m˙=0.1\dot{m} = 0.1 kg/s with a heat loss of 5 kW. The enthalpies at inlet and exit are 2500 kJ/kg and 2350 kJ/kg, respectively. Assuming negligible velocity at inlet (C10C_1 \approx 0), the velocity (C2C_2) of steam (in m/s) at the nozzle exit is __________ (correct to two decimal places).
Schematic of a nozzle showing inlet state (h1, C1), mass flow rate m_dot, heat loss Q_dot, and exit state (h2, C2).
