Benzene (u=3.95 x10-4Pa-s) at 60°C is flowing in a 24.3mm steel pipe (absolute roughness =4.6 x10-5m from moody diagram) at the rate of 20L/min. The specific weight of the benzene is 8.62 =kN/m³. Calculate the pressure difference between two points 100m apart if the pipe is horizontal.
Good day.
Here is my question (7)
Water flows through a horizontal pipe at the rate of 800 gal per min. What is the difference in pressure between a point where the diameter is 2 in. and a point where the diameter is 1 in.?
Nitrogen gas under a pressure pn = 15 psig is used for pumping kerosene at 25°C (density = 816 kg/m3, viscosity = 1.81 cP) through an elevation increase of 6 m. If there is an effective length of 45 m of nominal 2-in. schedule No. 40 pipe (commercial steel) between the two tanks, what is the flow rate of kerosene? Neglect exit kinetic-energy effects.
