Hello, i have an example question with an answer already given. Please help me in finding its solution so i can review and see the process and understand the concept. Thank you very much1.Question: Water at 15°C is pumped from a reservior at a rate of 0.1131 m3/s where the local atmospheric pressure is 94.6 kPa. The total head loss in the suction pipe is 1 m. From the manufacturer data, the NPSHrequired at this operating point is 7.8. Determine the maximum height hs (meters) before cavitation can occur. Round off your answer to 3 decimal places.Answer: 0.669
Albert bought a portable device to pump his truck tyres. On the manual, he found out that the device is a single stage, single-acting air compressor. Air delivery for thisdevice is 30 bar at a speed of 1500 rev/min. The atmospheric c ondition of his location is 87 kPa and 20 ˚C, with a FAD of 0.22 m2/min. The clearance volume is 4% of theswept volume and the stoke/bore ratio is 1.3/1.Take “n” as 1.3, cp = 1.005 kJ/kg K, cv = 0.718 kJ/kg K Calculate 1 What is the delivery volume in terms of stroke volume, provide the coefficient values of the swept volume to 4 decimal places? 2 What is the delivery isothermal efficiency of the compressor percentages to 2 decimal places? 3 What is the induced volume per stroke in m3 to 6 decimal places?

PROBLEM 02: Water entering a pump through an 200mm diameter pipe at 27.6 kPa has a flow rate of 0.1 m^3/s. It leaves the pump through a 100mm diameter pipe at 103.4 kPa. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump (746 watts = 1 HP). Illustrate the problem and show your complete solution.
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.

Provide solutions A penstock with a diameter of 4 ft and length of 225 ft carries water (γ = 62.4 lbf/ft3) through a 200 ft drop from a reservoir to a turbine. The penstock entrance is 10 ft below the water surface. The ﬂow rate through the system is 500 cfs and water exits the turbine in a free jet with a velocity of 9 ft/s. The Darcy-Weisbach friction factor for the penstock is 0.01. Flow is turbulent and head losses at the entrances and exits of the penstock and turbine are negligible. (a) Draw the hydraulic grade line and energy grade line. Label transitions points with the height change using symbols (e.g. hL for pipe head loss) (b) Determine the head delivered to the turbine by the water in ft.(c) If the turbine and generator have a combined eﬃciency of 80%, determine the power in hp generated by the system.
