Water and oil flow in horizontal pipelines. A double U- tube manometer is connected between the pipelines as shown in the figure. Calculate the pressure difference between the water pipe and the oil pipe. Water 15

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!

Consider the piping system shown . The average speed of water flowing through the 600-mm-diameter section of the piping system is 5 m/s. What is the volume flow rate of water in the piping system? Express the volume flow rate in L/s. For the case of steady flow of water through the piping system, what is the average speed of water in the 300-mm-diameter section of the system?

A 12-inch by 6-inch Venturi meter is installed in a vertical pipeline carrying water as shown inthe Figure C. The flow is upward through the meter. A differential manometer containing fluid,with sp.gr 1.67, is attached to inlet and throat, the difference z in gage levels being 5.76 ft.Neglecting loss of head, write energy equation from inlet to throat of meter. Also write stepby step equation of the differential gage between inlet and throat and combine the twoequations to compute the discharge
