Calculate the resistance of the hose

Reference no: EM13339659

Concrete is pumped from a cement mixer to the place it is being laid, instead of being carried in wheelbarrows. The flow rate is 160 L/min through a 50.0 m long, 8.00 cm diameter hose, and the pressure at the pump is8.40 ? 106 N/m2 (about 1200 psi).

(a) Calculate the resistance of the hose.

N·s/m5

(b) What is the viscosity of the concrete, assuming the flow is laminar?

(N/m2)·s

(c) How much power is being supplied, assuming the point of use is at the same level as the pump? You may neglect the power supplied to increase the concrete's velocity.
