%VY l. lin. 3. N Sheet 1.pdf → Sheet 1 Page 1 of 2 Q1/ An orifice meter is to be calibrated for the measurement of the flow rate of a stream of liquid acetone. The differential manometer fluid has a specific gravity of 1.10. The calibration is accomplished by connecting the orifice meter in series with a rotameter that has previously been calibrated for acetone, adjusting a valve to set the flow rate, and recording the flow rate (determined from the rotameter reading and the rotameter calibration curve) and the differential manometer reading, h. The procedure is repeated for several valve settings to generate an orifice meter calibration curve of flow rate versus h. The following data are taken.

oblems: 1. A horizontal pipe, 1 ft. in diameter, tapers gradually to 8 in. in diameter. If the flow is 500 cu ft. of water per minute, what is the difference between the pressures at the two sections? Ans. PA - PB = 443.63lb per sq ft 2. Water flows through a horizontal pipe at a velocity of 50 ft. per sec. Owing to the pipe gradually expanding to a larger size, the velocity decreases to 35 ft. per sec. What is the difference between the pressures at two points, one in each size of pipe? Ans. Pg - PA = 1,236. 75 lb per sq ft

Q1: Water flows in a circular pipe. At one section the diameter is 0.3 m the static pressure is 260 kpa gauge, the velocity is 3 m/s and the elevation is 10 m above ground level. The elevation at a section downstream is 0 m and the pipe diameter is 0.15 m. Find the gauge pressure at the downstream section. Frictional effect may be neglected. Assume density of water to be 999 kg/m³. *****************

Please show your complete solution. Thank you! Air flows in a steady flow manner through a converging tube. At the inlet the pressure is 690kPaabs and the density is 0.838 kg/cu.m. If air enters with a volume flow of 125 cu.m per min at the rate of 94 m/min and the exit section has a diameter of 350mm, determine a.) the mass flow rate, kg/min b.) the diameter of the entrance section and c.) the exit velocity. Assume that the density is constant.

1.1 A 6 inches pipe carrying 3.93 cfs connects to a 6 inches pipe. Find the velocity head in the 6 inches pipe. 1.2 Sulfur dioxide flows through a 12 inches discharge duct that reduces to 6 in diameter at discharge into a stack. The pressures in the duct and discharge stream are. respectively, 30.0 psi absolute and atmospheric (14.7 psi). The velocity in the duct is 50.0 ft/sec, and the temperature is 80 F. Calculate the velocity in the discharge stream if the temperature of the gas is 23 F. 1.3 Water flows through a horizontal 100-mm pipe under a pressure of 414 kPa.
