- An engineer who took college fluid mechanics on apass-fail basis has placed the static pressure hole farupstream of the stagnation probe, as in Fig, thuscontaminating the pitot measurement ridiculously withpipe friction losses. If the pipe flow is air at 20°C and1 atm and the manometer fluid is Meriam red oil (SG =0.827), estimate the air centerline velocity for the givenmanometer reading of 16 cm. Assume a smooth-walledtube.A long fi xed tube with a rounded nose, aligned with anoncoming fl ow, can be used to measure velocity. Measurementsare made of the pressure at (1) the front nose and(2) a hole in the side of the tube further along, where thepressure nearly equals stream pressure.( a ) Make a sketch of this device and show how the velocityis calculated. ( b ) For a particular sea-level airfl ow, the differencebetween nose pressure and side pressure is 1.5 lbf/in 2 .What is the air velocity, in mi/h?An air compressor increases the pressure (Pout > Pin) and the density (?out > ?in) of the air passing through it. For the case in which the outlet and inlet diameters are equal (Dout = Din), how does average air speed change across the compressor? In particular, is Vout less than, equal to, or greater than Vin? Explain.
- pls replyyy Air is flowing through a square conduit whose section changes from 100 mm (section 1) to 200 (section 2). At section 1, v1=6 m/s and the density at section 1 is 1 kg/m3. If the velocity of flow is 1.8 m/s at section 2, find the density of gas at section 2In order to measure the speed of the ambient air at atmospheric pressure, a Pitot tube is used, in which water is the gage fluid.. It is known that the ambient air speed is 25 meters per second, when the air temperature is 40 degrees. Celius. Calculate what the differential manometer reading in the pitot tube would be?In an industrial cooling process, water is circulated through a system. If water is pump from the first floor through a 6cm diameter pipe with a speed of 0.45 m/s under a pressure of 400torr, what will be the pressure on the nest floor 4m above into a pipe with diameter 2cm? Show your solution
- Air velocity in a duct is measured as 38.2 m/s by a pitot tube. Density of flowing air 1.3 kg/m3. If the pressure difference recorded by the pitot static tube is 0.1 m of water, calculate the coefficient of velocity of the pitot static tube. A Figure or Free Body Diagram will be much appreciated. Thank you1. Assume a horizontal shaft handling water at 65 deg C (Pv=2.503 KPa, Density=980.5 m3/kg). The suction nozzle is 4.35 m below the pump centerline and the pressure gauge reading at this point is 221Kpag. Determine the NPSHa if the head loss is 0.82 m. If the NPSHr is 3m less than the NPSHa you got on question number 1, determine the pump suction specific speed at pump rotating at 1800rpm and Q=500gpmI've been struggling about this problem. How can I get the fluid velocity from the Reynolds numbers. That is the required value for Re. If, the given values are Water Density = 10000 kg/m3, Diameter of tube = 0.05m and Dynamic Viscosity = 0.001 Pa-s. If the formula is Re = Vρd/μ.
- The 28-in-diameter pump in Fig. at 1170 r/min isused to pump water at 20°C through a piping system at14,000 gal/min. (a) Determine the required brake horsepower.The average friction factor is 0.018. (b) If there is65 ft of 12-in-diameter pipe upstream of the pump, how farbelow the surface should the pump inlet be placed to avoidcavitation?A pitot-static probe will be used to measure the velocitydistribution in a water tunnel at 20°C. The two pressurelines from the probe will be connected to a U-tube manometerthat uses a liquid of specifi c gravity 1.7. The maximumvelocity expected in the water tunnel is 2.3 m/s. Your job isto select an appropriate U-tube from a manufacturer thatsupplies manometers of heights 8, 12, 16, 24, and 36 in.The cost increases signifi cantly with manometer height.Which of these should you purchase?A pump is being used to transport a liquid food product (density = 1000 Kg/m3, viscosity= 1.2 x 10 -3 Pa-s) from a holding tank to a filling machine at a mass flow rate of 2 Kg/s. The liquid level at the holding tank is 5 m above the pump, and the filling machine is 10 m above the pump. There is 100 m of 2 inch nominal diameter sanitary pipeline (assume: commercial steel) between the holding tank and the filling machine with one open glove valve and three medium sweep 90oelbows in the system. Determine the theoretical power requirement of the pump if the efficiency is 75%. Answer: 234 Watts. Show the solution.
