QUESTION 3 In the Austrian Alps, a restaurant rather high in the mountains gets its water from a very wide reservoir several hundred meters lower, the difference in elevation between restaurant and reservoir being denoted by H. The water is pumped upwards by a pump next to the reservoir. Under steady-state conditions, the volumetric flow rate through the pressure line is denoted by ø, while øw denotes the pumping power to realise this Øy. With such a long pipeline, energy dissipation by friction in the line can't be ignored. Energy dissipation in the pump is substantial but can be left out of consideration for now. Heat exchange with the surroundings may be ignored as well. Water density may be taken as being constant. Questions: a) Draw up a mechanical energy balance between point 1 at the surface of the reservoir and point 2 right after the pump to find an expression for the pressure at point 2. b) Draw up a mechanical energy balance between point 2 right after the pump and point 3…

You are working for a medical device start-up company as a design engineer. Your first task is to make measurements on the flow of blood plasma through your prototype. The device specifications require that 37°C plasma flow into the device pass through a bank of 100 tubes (0.2mm diameter), then exit the device. The total flow rate for the device must be 800 ml min^-1. If you want to maintain a pressure drop across each tube below 100 pascals, what is the maximum length of the tube in centimeters?

You are being tasked as a wind tunnel engineer to investigate the performance of newly designed high-speed wind tunnel in UPNM. An exhaust gas flows through a nozzle where the inlet area is 5,000 cm2.At this inlet, the gas has a velocity of 1,200 m/s, temperature of 1,500oC,and pressure of 6,000 kPa. Initial measurement revealed that the pressure at the exit of the wind tunnel is 100 kPa. Based on this information, analyze and investigate ; i. Mach number at inlet of the nozzle ii. The velocity of gas at exit iii. The area of the nozzle at exit Take specific heat ratio for the exhaust gas, ? to be 1.7 and the gas constant, R to be 205 J/kg.
7.1 To measure the mass flow rate of a fluid in a laminar flow through a circular pipe, a hot-wire-type velocity meter is placed in the center of the pipe. Assuming that the measuring station is far from the entrance of the pipe, the velocity distribution is parabolic: where is the centerline velocity (r = 0), r is the radial distance from the pipe centerline, and D is the pipe diameter. Derive an expression for the average fluid velocity at the cross section in terms of and D. (b) Obtain an expression for the mass flow rate. (c) If the fluid is mercury at , D = 10 cm, and the measured value of is 0.2 cm/s, calculate the mass flow rate from the measurement.
