If the exit area of the nozzle is 3 times the throat area, determine (a) the back pressure to produce a normal shock at the exit plane of the nozzle. This area will then be the nozzle exit area. Mach number is the ratio of the gas velocity to the local speed of sound. The Mach number at the nozzle exit is given by a perfect gas expansion expression P c is the pressure in the combustion chamber and P atm is atmospheric pressure, or 14.7 psi. Previously we used the steady flow energy equation to relate the exhaust velocity of a rocket motor, Figure 14.1, to the conditions in the combustion chamber and the exit pressure. Figure 14.1: Schematic of rocket nozzle and combustion chamber Nozzle Calculation Design The exit velocity of the nozzle can determined by the energy balance of the nozzle. In steady-flow condition, it is. The above analysis shows that in order to calculate the exit velocity, temperatures at state 4 and state 5 need to be determined first.Calculate the gain of the process if the proportional band setting is at 40%. . UNIT 6 EXAM In a differential pressure flow meter, the velocity of a fluid leaving the orifices plate is _____ the . UNIT 6 EXAM As the velocity of the fluid increases, the resistance of the unshielded thermistor sensor head...not yet reached its final velocity. In accordance with Equation (9-2),the cross-sectionalarea of the stream must be larger where the velocity of flow is smaller. Ifwe wish to calculate the quantity of liquid flowing out of the tank persecond, we mayapply Equation (9-1)totheresult obtainedin Equation (9-4), obtaining so that. Q = Av, Q = AV2gh. This preview shows page 14 - 17 out of 18 pages. (a) Calculate the nozzle exit velocity.

Purdue University.If the mass (kg) of the deflector is 0,5 kg. Determine the velocity of water entering the system. A Stream of water from a 45-mm-diameter nozzle strikes a curved vane, as shown in figure below. A stagnation tube connected to a mercury-filled U-tube manometer is located at the nozzle exit plane. Calculate the speed of the water leaving the nozzle. properties of a nozzle (the thrust is the mass-flow-rate times the exit speed, F mv = e) are: • Nozzle size, given by the exit area, e; the actual area law, provided the entry area is large enough . A that the entry speed can be neglected, only modifies the flow inside the nozzle, but not the exit conditions. This preview shows page 14 - 17 out of 18 pages.

Purdue University.Jun 20, 2019 · Calculate mass rate of flow of steam through the nozzle. ME8595 Important 8 marks Questions THERMAL ENGINEERING II (a) Dry saturated steam enters a frictionless adiabatic nozzle with negligible velocity at a temperature of 300oC. It is expanded to pressure of 5000 KPa. The mass flow rate is 1 kg/s. Calculate the exit velocity of the steam. cross-stream velocity component and its fluctuations just upstream of the nozzle exit. The results indicate that minor differences in velocity and velocity fluctuations near the nozzle exit can lead to major variations in free-surface geometry, and that free-surface fluctuations are strongly affected by changes in flow conditioner design, 137.37 m/s but in second nozzle with exit diameter 53 cm the increase in velocity from inlet to exit is 152.6 m/s. This represents that velocity at exit increases with decrease in diameter. The nozzle with exit diameter 53 cm gives maximum mach number at exit compared to the nozzle with 60 cm diameter. 4. Flow analysis for various divergent angle The viscosity-dependence of the velocity coefficient for a free liquid jet, issuing from a sharp-edged orifice, is predicted by computing the dissipation of energy in the boundary layer on the back of the orifice plate. The prediction is upheld by the only known direct measurements of velocity coefficients. interactive graduated cylinder practice -8Ls
