- SAE 30 oil is contained in a cylinder with inside diameter of 1 in. and length of 1 ft. What is the pressure required to decrease the volume of the oil by 2%?) Consider a double - fluid manometer attached to an air pipe shown in Figure. If the specific gravity of one fluid is 13.55, determine the specific gravity of the other fluid for the indicated absolute pressure of air. Take the atmospheric pressure to be 100 kPa. (Refer to the flow shown in the figure. The velocity before the contraction is 1.51m/s. Given: h=0.20m D1=0.103m D2=0.057m Determine the height of the fluid in the manometer, H, in meters
- Pitot PipeBy connecting a mercury pressure gauge to a vertical pipeline through which water is transmitted, speed measurement is performed with a pitot tube. Since the deviation from the pressure gauge column is 15 cm, calculate the speed of the water in the pipe. (Pmercury=13560 kg/m3, Pwater=1000 kg/m3) (Answer is V2=6.08 m/s)The Venturi meter shown in the sketch below, contracts the flow down to one quarter of its original area. Cold air at 0 deg C flows in the pipe through the Venturi meter. The velocity of the air upstream of the Venturi meter is equal to 40 ft/s and the pressure at the same point is equal to 30 psia. What is the manometer reading if the fluid of the manometer is water with density 1000 kg/m3 . Assume that the air behaves as an ideal gas with molecular weight equal to Mw=29 kg/kmol and constant density evaluated at upstream conditions. Use Bernoulli's equation for your calculations. please respond asap!Show complete solutions and figures. The shown tank with an attached manometer contains water unit weight is 9.79 kN/cu.m.at 200oC. The atmospheric pressure is 100kPa. There is a valve located 1m from the surface of the water in the manometer. The valve is closed trapping the air in the manometer, and the water is added to the tank to the level of the valve. Find the increase in the elevation of the water in the manometer assuming the air in the manometer is compressed isothermally. a) 101.3mm b) 92.7mm c) 73.2mm d) 82.4mm e) None
- Please show the complete solution. (Example: Conversion of Units) A rigid container is closed at one end and measures 8 in diameter by 12 in long. The container is held vertical and is slowly moved downward until the pressure in the container is 17 psia. What will be the depth of the top of the container from the free water surface?1. In calibrating a 10-mL pipet, a measured volume of water was transferred to a tared flask and weighed, yielding a mass of 9.9814 g. (a) Calculate, with and without correcting for buoyancy, the volume of water delivered by the pipet. Assume that the density of water is 0.99707 g/cm3 and that the density of the weights is 8.40 g/cm3. (b) What are the absolute and relative errors introduced by failing to account for the effect of buoyancy? Is this a significant source of determinate error for the calibration of a pipet? Explain. 2. Repeat the questions in problem 1 for the case when a mass of 0.2500 g is measured for a solid that has a density of 2.50 g/cm3. 3. Is the failure to correct for buoyancy a constant or proportional source of determinate error?A manometer is used to measure the pressure in a tank filled with air. The fluid has a specific gravity of 0.95, and the manometer column height is 65cm. If the local atmospheric pressure is 96 kPa, determine the absolute pressure within the tank. answer in kPa abs
- The manometer depicted below is mounted on a city water supply pipe to monitor water pressure. However, the field engineer suspects the manometer reading of h = 3 feet (Hg) may be incorrect. If the pressure in the pipe is measured independently and found to be 18.6 lb/in. (psi), The specific gravity of Hg is 13.6. determine the correct value of the reading h.As shown in the figure, water flows in the horizontal pipe. The pipe consists of two different sections, 60 mm and 30 mm in diameter, connected by a smooth reduction. The pressure difference between the two sections is measured with a mercury manometer. Friction effects are neglected. The height between the mercury levels in the two sections of the pipe was determined as 1.4m. Find the velocity and mass flow at points 1 and 2. (Density of mercury: 13.6 grams / cm3, Density of water: 1gr / cm3)To keep track of water pressure, a manometer is attached to a water supply pipe. The 3 ft (Hg) measurement on the manometer, on the other hand, could be inaccurate. Determine the right value of the reading (h) if the pressure in the pipe is measured and determined to be 18.6 lb/in² (psi). The specific gravity of Hg is 13.6.
