Air Steadily Enters A Nozzle At An Absolute Pressure Of 110 Kpa And A Temperature Of 60 With A Velocity Of 3 M S Stat 1 (160.18 KiB) Viewed 45 times

Air steadily enters a nozzle at an absolute pressure of 110 kPa and a temperature of 60°℃ with a velocity of 3 m/s (State 1). The volumetric flow rate at the inlet is 0.0283 m³/s. Air exits the nozzle at an absolute pressure of 100 kPa and a temperature of 60°C with a velocity of 15 m/s (State 2). (a) Calculate the mass flow rate of air, in kg/s. (b) Find the ratio of cross-sectional area at inlet to exit, A₁/A2. (c) Determine the rate of heat transfer for the nozzle, in W. HW-12 (ii) Liquid water steadily flows through a constant diameter pipe from a reservoir at an altitude of 2000 m (State 1) to another reservoir at an altitude of 1000 m (State 2). Water enters the pipe at 25°C. Consider that the pipe is rigid and perfectly insulated and that there is negligible pressure drop across the pipe. Calculate the temperature of liquid water at the exit, in °C.
