5. A horizontal nozzle has an inlet velocity up and an outlet velocity u₂ and discharges into the atmosphere. Show that the velocity at exit is given by the following formulae. U₂ = {24p/p+u₁²}% U₂ = {2gAh + u₂²)% and

3. A pipe with varying cross-sectional areas is set up vertically as shown in the drawing. Water enters the pipe from the top wider end at a speed of 300 cm/s. Calculate (a) the mass flow rate of water (the amount of mass entering/exiting the piper every second) and (b) the water pressure at the bottom narrower end section of the piper. (Density of water is p = 1000 kg/m2 1.00 g/cm')) P 1.20x10 Pa 10.0 cm h=4.00 m 2.50 cm2 P= ?

100% High pressure water and compressed air are delivered to some operating rooms. Bored one day, with no patients around, you take the cap off the nozzle to see what would happen. Water flows through the vertical pipe and nozzle and then exhausts into the air as shown in the diagram. The water pressure in the pipe at position 1 is 3 atm. The pressure when the water discharges to the air is 1 atm. Position 2 identifies the nozzle, 0.75 m above position 1, where the water flow has been constricted from an 8-cm diameter pipe to a 3-cm diameter nozzle. Assume that the free jet remains a stream of water with a 3-cm diameter. Assume no friction losses. Free jet -3 cm diameter 0.75 m a) Determine the mass flow rate of water through pipe at position 1 in kg/s. 3 atm 8 cm diameter b) Determine the height, h, the water jet can rise. c) Calculate the friction factor inside the 8-cm pipe and determine if the assumptions of negligible friction losses was reasonable.

Q5: A converging-diverging nozzle, which is shown in the figure, is supplied with air from a large tank where the pressure is Po and exhausts to the atmosphere with a pressure of Po. The area A at distance x from the throat is given by (A = At (1 + 0.75x/L)), where At is the throat cross- sectional area and Lis the total length of the diverging part of the nozzle. At a certain pressure ratio PoPb, a normal shock wave stands in the nozzle at a point where the Mach number before the shock is 1.7. Find the position of the normal shock wave from the throat, and the pressure ratio P/Po. Ans.: 0.45 L = 0.753 Р. Ps

Explain the steps in simple way so that i can understand the problem. Kindly don't use Ai ,It is Important one.

a. Calculate the mass flow rate in lb/min. b. Calculate the speed at section 2 in ft/min or fpm

BOILER |Pump Exit T, = 40°C P1 = 15.0 MPa Boiler Exit T2 = 550°C P2 = 15.0 MPa The pump shown in the figure is used to pump 36,000 kg of compressed liquid water per hour into a boiler. Pump exit conditions are 40 °C and 15.0 MPa. The boiler discharges steam at 550 °C and 15.0 MPa (mass flow of steam discharged equals mass flow of water pumped in). Find the rate at which heat must be generated by the boiler, Q , in units of MW (1 MW = 1 million Watts). MW
