1. Air flow isentropically through a converging nozzle attached to a reservoir, where the pressure is 170 kPa and temperature is 300 K. At the inlet to the nozzle the Mach number is 0.2, the nozzle discharge to the atmosphere (10OKPA). The discharge area is 0.02 m?. Determine the magnitude and direction of the force that must be applied to hold the nozzle in place.

Q1) Air is to be expanded to Mach number (2.0) in a convergent-divergent nozzle from an inlet velocity of (100 m/s). The inlet area is (50cm³). Inlet static temperature is (500K) and static pressure is 101.3 kpa. Assuming isentropic flow determine: 1. The Mach number at the inlet. 2. The stagnation pressure and temperature. 3. The temperature and pressure at the throat. 4. The velocity and temperature at exit. 5. The throat and exit temperature. 6. The mass flow rate.

Air flows through a long, isentropic nozzle. The temperature and pressure at the * reservoir are 1000K and 20 atm, respectively. If the Mach number at the entrance is 0.2, determine the gas velocity at the entrance. 634 m/s 127 m/s 478 m/s 254 m/s For a large centrifugal pump, the required net positive suction head is typically around 5 ft 2 ft 15 ft

Air enters a 5-cm-diameter duct at Mach number = 0.2, a temperature of 550 K and a pressure of 200 kPa. The average friction factor for the duct is 0.016. If the Mach number at the duct exit is 0.8, determine the pressure at the duct exit. (For air constant R = 287 J/kg.K, specific heat ratio K = 1.4). Select one: a. 65.95 kPa b. 54.85 kPa c. 80.75 kPa d. 47.27 kPa

Find what is needed and make sure that the solution is correct as shown in the answer to the question

! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam enters a converging nozzle at 5.0 MPa and 400°C with a negligible velocity, and it exits at 3.0 MPa. It has a nozzle exit area of 50 cm². Determine the exit velocity, mass flow rate, and exit Mach number if the nozzle is isentropic. The exit velocity is m/s. kg/s. The mass flow rate is The exit Mach number is
