Water is flowing at 0.075 cu.m./sec through a glazed porcelain pipe 400m long and 200mm diameter. The pipe roughness is 0.0015mm. Properties of water: Density: 1,000 g/cu.m., viscosity = 0.001 N-m/sec.         What is the velocity of water in the pipe? What is the Reynold's number? Steady State flow exists in pipe that undergoes a gradual expansion from a diameter of 6in. Assuming constant density and the inlet flow velocity is 22.4 ft/sec. What is the size of the exit pipe if the exist flow velocity is 12.6 ft/sec?

Can I have a detailed, step-by-step explanation for the following question? Thank you! The answer is given as, q = sqrt [ (2*sigma*g*h)/(rho) ], which is not the answer I got. Can someone clarify?

This question please

As a process engineer, you are designing a new drinking water treatment plant using conventional treatment process including Two Rapid Mixers as follows: The design flow is 50 million gallons per day (MGD) (1 Gallon = 3.785 L, 1 m³ = 1000 L). The average temperature of water is 5°C with a dynamic viscosity, μ = 1.519 x 10-3 Pa.Sec In each rapid mixer with a square shape, detention time, e = 1 min, water depth H = 13 ft, and power input P = 1.5 kw (1 ft = 0.3048 m, 1 KW = 1,000 W) The equivalent diameter, TE for each rapid mixer is ________ m.

1.) A process fluid (μ = 3 cP, p = 1210 kg/m³) is flowing through a 5.8-cm ID pipe with an average velocity (Uavg) of 2.5 m/sec. Calculate/estimate the following: a) What is the velocity profile from the center of the pipe (r=0 cm) to the pipe wall (r; = 2.9 cm)? b) The length of the pipe (4) is 10 feet. Calculate the pressure drop through the pipe using the Hagen-Poiseuille law. c) Calculate the Reynolds number for this system. d) Is the flow in the pipe laminar or turbulent? e) Estimate the Fanning friction factor (f) in this system. f) What is the pressure drop (AP) in the system if friction is considered?
