- 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.

The velocity of flow through the pipeline is 5m/s and the energy loss due to friction in the pipeline is 200J/kg. The water leaves the turbine at atmospheric pressure (100 kN/m2) and with negligible velocity. Assuming an efficiency of 85% for the turbine, determine: a). Pipeline diameter b). Pressure at entry to turbine c). Turbine power output. Take f = 0.025arrow_forwardHi please help me answer this question with complete solutionarrow_forward

Calculate the turbine exit pressure and the actual expansion index (n).arrow_forwardProblem (6.1) Steam at 1.8 MPa and 275 °C expands through a convergent- divergent nozzle to 0.1 MPa. If there is 10 % loss in energy between the throat and the nozzle exit and the vapor flow rate is 0.5 kg/s, determine the cross- sectional area of the throat and the nozzle exit.arrow_forward2. An ideal gas, following the relationship (Pv = 75 m2/s²), flows in a horizontal pipe at a constant temperature. The internal diameter of the pipe is 0.025 m and the pressure drop is 11 kPa for each 5m length. Calculate the mass flow rate per unit area in kg/sm2, assuming the pressure at the end of the pipe is 12 kpa and the friction factor f = 0.009. Ignore the kinetic energy.arrow_forward
- A steady stream of n-butanol is needed to be fed into the reactor at 40 ̊C. However, the inlet of the reactor is located 7.5 m above the reservoir tank. As such, a highly effective centrifugal pump (70% efficiency) is used for such a purpose. It was understood that the needed volumetric flow rate into the reactor is fixed at 20 m3/h. It was also noted that the n-butanol reservoir is closed but not pressurized, while the gauge pressure at the endof the discharge line is measured at 275 kPa. Given that the density of n-butanol is 810kg/m3. If the discharge pipeline was 5 cm in diameter, calculate: (i) The velocity of n-butanol at the discharge line. (ii) The total power input from the centrifugal pump. (iii) The power delivered to the n-butanol fluid.arrow_forwardChoose the following and define alsoarrow_forwardThe power output of a steam turbine is 5 MW.
