Problem 2: Calculation of the Flow Rate in a Pipeline Figure 1 shows a pipeline which delivers liquid at constant temperature T from point 1, where the pressure is p, and the elevation is z, to point 2, where the pressure is p2 and the elevation 2₂. The effective length of the pipeline, including fittings and expansion losses, is L and its diameter is D. P = P₁ 44 2 -P= P₂ ܕܐ=ܐ Z= Z₁ Figure 1. Liquid Flow in a Pipeline (a) Calculate the flow rate q (in gal/min) in the pipeline for water at 60°F. The pipeline is nominal 6-inch diameter schedule 40 commercial steel pipe with L = 5000 ft, p= 150 psig, pz = 0 psig, z; = 0 ft, z₂ = 300 ft. (b) Do the calculations for several higher values of p: (200 psig max). Plot the calculated flow rate as a function of pressure difference. Based on the plot, determine the minimum pressure difference needed to start the flow.

Please do these two questions Thanks in advance
(Bernoulli/continuity/Pitot tube) Two Pitot tubes and two static pressure taps are placed in the pipe contraction shown in the figure below. The flowing fluid is water, and viscous effects are negligible. Determine the two manometer readings, h and H. V=2.2 ft/s h= H= 6.3 in. Air SG= 1.10 ft •ft H 3.5 in. h
Determine a. Velocity at the pipe with 8 in. diameter in ft/s. b. Pressure at point D in psi c. Flow rate in cfs d. Velocity at the pipe with 18 in. diameter in ft/s
I need the answer to the question in fluids
An orifice meter is a device used to determine the flow velocity and flow rate in a pipe. The meter is connected to a U-tube manometer shown in Figure 2(a). The meter is connected to a U-tube manometer shown in Figure 2(b). Derive the equation for the flow rate, Q in the horizontal pipe.
Given A fluid with sg = 0.74 is flowing at 0.089 m3/s in the fabricated tube shown in the figure. The pressure in the tube before the contraction is 475 kPa. Refer to Appendix G.2. Flow 80-mm OD x 2.8-mm wall steel tube 160-mm OD x 5.5-mm wall steel tube Required Calculate the pressure in the smaller tube, to the nearest 10th. Your Answer:
(Bernoulli/continuity/Pitot tube) Two Pitot tubes and two static pressure taps are placed in the pipe contraction shown in the figure below. The flowing fluid is water, and viscous effects are negligible. Determine the two manometer readings, h and H. V=1.7 ft/s h = H= 6.4 in. Air ↓ SG= 1.10 ft ft TH 3.8 in.
Please show all work including unit converstions and please make sure to show all units. For P1=10+(6), so P1=16 psi for P2=20+0, so P2=20 psi for D1= 1ft for D2=0.6ft for Q=5.4 cubic ft per second
