Nozzle is a device that can be used to O A. increase the mass flow rate O B. reduce the mass flow rate O C. increase the exit velocity O D. reduce the exit velocity

i need the answer quickly

At the inlet to a certain nozzle the enthalpy of fluid passing is 2800 KJKG. In addition, the velocity is 50 ms. At the discharge end, the enthalpy is 2600 kJAg. The nozzle is horizontal and there is negligible heat loss from it. a. Find the velocity at the exit of the nozzle? b. If the inlet area is 900 cm² and specific vohme at the inlet is 0.187 m'kg, find the mass flowrate? c. If the specific volume at the exit of the nozzle is 0.498 m'/kg, find the exit area of nozzle? Fhuid in Fhaid out V2= ? A2= ? V- 50 m/s A- 900 cm? hi- 2800 kJkg h2= 2600 kJ/kg

i need correct explanation my best wishes ton
