Water (density = 1000 kg/m3) flows through a duct that makes a 180 degree U-shaped bend (see below). Assume that the fluid is incompressible through the duct and the velocity at the inlet is V1 = 24 m/s. Assume that the momentum-flux correction factor at both inlet (point 1) and outlet (point 2) is 2.1. The gage pressures are P1 = 120 kPa at the inlet and P2 = 248 kPa at the outlet of the bend. The inlet is...

An organic liquid is heated from 20°C to 40°C by hot water in a 1:1 pass shell-and- tube heat exchanger in counter-current flow. The inlet temperature of the water stream is 85oC and flows in the shell side. The organic liquid flows through a bundle of 200 tubes of outside diameter 21 mm with a wall thickness of 2 mm. The flows of the organic liquid and water are 40 kg s and 15 kg s1, respectively (a) Calculate the...

Problem 3: (35pts) Atmospheric air enters the heated section of a circular tube at a flow rate of 0.005 kg/s and a temperature of 30°C. The tube is of diameter D =60mm, and fully developed conditions with h = 30W/m2K exist over the entire length of L-4m. Take cp-1015 /kg.K 2 (a) (10pts) For the case of uniform surface heat flux at q"-1000W/m, determine the total heat transfer rate q and the mean temperature of the air leaving the tube...

Liquid saline flows steadily along the duct in Figure 1, which is part of an infusion set. The duct has constant cross-sectional area Ao-18 mm. The fluid velocity at the inlet section is Vo 0.35 m/s. A drug is added to the saline through a side port connected to the main duct at an angle θ 45°. The cross-sectional area of the side access is A1-10 mm2 and the drug is injected with velocity V,-0.8 m/s. The drug has the...

3. The outdoor air enters an AC system at 10°C and 75% relative humidity at a steady rate of 26 m3/ min, and it leaves at 25°C and 45% relative humidity. The outdoor air is first heated to 21°C in the heating section and then humidified by injection of hot steam in the humidifying section. Assuming the entire process takes place at 1 atm, determine (a) the rate of heat supply in the heating section, and (b) the mass flow...

5.(14 marks total) The sketch shows a system for producing superheated steam from hot liquid water. A steady flow of saturated liquid water enters at 1 at a pressure of P, = 200 kPa and passes through a valve which reduces the pressure to P, = 100 kPa. The resulting mixture enters a separation tank, from which saturated vapour at 4 flows out to a compressor which compresses it to Ps = 300 kPa, while saturated liquid at 3 is...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
