flowing with water at temperatures of 30 ^o C and 40 ^o C. Calculate the maximum velocity under conditions  A.Laminar B.Turbulent

A pitot-static tube is used to measure the velocity of water in a pipe. The stagnation pressure head is 10 m and static pressure head is 8 m. Calculate the velocity of flow if the coefficient of pitot tube equal to 0.95

fast.

The Figure shown below is a parallel pipeline system with two branches used to supply lubricating water to the bearings. The main line and two branches use the same size of pipes. The pressures at section 1 and section 2 are   and  ,  respectively. The resistance coefficients for two bearings are   and  .  The cross section areas of two branch pipes are   .  The energy loss caused by friction can be ignored. The energy loss caused by one bend is  . (4)   Calculate the energy loss    for branch b_________

Q: Pressure drop in slug flow-M. A light oil and a gas are flowing upward in a vertical tube of 4.0-in. I.D. at superficial velocities of L/A 1.2 ft/sec and G/A = 4.8 ft/sec, = respectively. The viscosities of the oil and gas are 15.6 and 0.038... Posted one year ago

8.2 Water at 35°C is pumped through a horizontal, 200-m-long, 30-mm-diameter tube at o.25 kg/s. Over time, a 2-mm-thick layer of scale of surface roughness e = 200 µm is deposited on the interior tube wall. Determine the pressure drop from the entrance to the exit of the tube and the required pump power for the clean and fouled conditions.

At approximately what volume flow rate will propyl alcohol at 77 °F become turbulent when flowing in a 3-in Type K copper tube?

Specifications: The total length of pipe in the three inch branch is 10 ft, and the length of pipe in the one inch branch is 8 ft. Brine (sg=1.04, m=10-3Pa*s) flows at 250gpm through the entrance at point A. Assume fully turbulent flow in both branches (f=ft). Pipes are standard Schedule 40 steel pipes. Assume the globe valve is partially shut so its equivalent L/D is 1000. For Part 1 of this project, you are tasked with determining the following: The flow rate in both branches The pressure drop in both branches The overall resistance coefficient

Plz correct solution.

a) Calculate the maximum flux the liquid water can have ( η = 0.891 cP and ρ = 0.998 g/mL a 20 ºC) when flowing through a 2 mm diameter tube, in the laminar regime.b) If the pressure when entering the tube is 1 bar, how many meters will it need for the pressure to decrease a 10%? Data: dina/cm3 = 10 Pa/m; 1 bar = 105 Pa.  Results: 2.81 cm3/s, 1.57 m
