QUESTION:

Problem 55PE

Concrete is pumped from a cement mixer to the place it is being laid, instead of being carried in wheelbarrows. The flow rate is 200.0 L/min through a 50.0-m-long, 8.00-cm-diameter hose, and the pressure at the pump is 8.00×106 N/m2 . Verify that the flow of concrete is laminar taking concrete’s viscosity to be 48.0 (N/m2) · s , and given its density is 2300 kg/m3 .
