Question

A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume at inlet is 0.19 m3/kg, find the rate of flow of fluid (iii) If the specific volume at the nozzle exit is 0.5 m3/kg, find the exit area of the nozzle.

Step 1

Step 1: Calculate the velocity at the nozzle exit using the steady flow energy equation: \[m_1 \cdot h_1 + \frac{v_1^2}{2000} = m_2 \cdot h_2 + \frac{v_2^2}{2000}\] Given: \(h_1 = 3025 \, \text{kJ/kg}\), \(v_1 = 60 \, \text{m/s}\), \(h_2 = 2790 \, Show more…
