Water at 10 °C (p = 999.7kg/m3 and μ = 1.307×10-3kg/ms) is flowing steadily in a 0.12-cm-diameter, 15-m-long pipe at an average velocity of 0.9 m/s. Determine
Water at 10 °C (p = 999.7kg/m3 and μ = 1.307×10-3kg/ms) is flowing steadily in a 0.12-cm-diameter, 15-m-long pipe at an average velocity of 0.9 m/s. Determine (a) the Reynolds number and decide weather the flow is laminar or turbulent (b) the head loss, (c) the pressure drop, and (d) the pumping power requirement to overcome this pressure drop.

In a hydroelectric power station, the turbine is driven by water flowing from a reservoir at the rate of 551 m s. The water is pumped through a pipe 2.06 km long of 2.53 m intemal diameter with a friction factor of 0.004. The water is assumed to have a kinematic viscosity of 13x10 mʻls. The elevation of the upper reservoir above sea level is 400 m and that of the lower reservoir is 40 m. Determine the following Mean...

5.16. Water is flowing in a 3-cm-diameter pipe at an average velocity of Uav 2 m/s. Assuming water density of ρ-1000 kg/m 3 and viscosity μ-10-3 N s'm2, calculate the velocity at the center of the pipe, the shear τ at the wall, and the Reynolds number. Assuming laminar flow, calculate friction coefficient C and pressure drop dp/dx.
A light oil is flowing through a commercial steel pipe of diameter D1. The head available...
A light oil is flowing through a commercial steel pipe of diameter D1. The head available to produce flow is independent of the flow rate. It is decided to utilise this head to increase the oil flow rate fourfold by installing a second pipe in parallel with the first pipe and of the same length. What should the diameter of the second pipe be, if: (i) flow in each of the two pipes is highly turbulent and the same roughness...

P6.67 P6.50 Water at 20°C is to be delivered through a 10-cm- diameter smooth pipe with an average velocity of 0.1 m/s S. (a) Check that the flow is turbulent. (b) Find the frictional head loss per length of pipe. (c) If the flow is mistaken to be laminar, and the formula f 64/Rea is used, how large would be the error in calculating the answer to (b)?

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

Question (a) Sulphuric acid is flowing through a pipe (2.5 inch diameter, 50 ft length) in a velocity of 0.006 m2/s. The sulphuric acid has a viscosity of 25 mN.s/m² and density of 1680 kg/m² while the roughness of the pipe surface is 1.3 mm. If the operating temperature is 290K, determine fluid flow (i.e. laminar, turbulent or others). (Given that 1 m= 39.37 inch) (b) Define pump, suction head, impelling head and the total head of a pump. (c)...
