Product description
Gear pump A pumps mineral oil into an open tank B with a constant level of H = 35m. The diameter of the pipeline d = 0.05m, oil flow Q = 50l / min, the length of the pipeline l = 200m. kinematic viscosity coefficient υ = 0.1cm2 / s. Determine what gauge pressure the pump will create at the beginning of the pipeline.
Directions Local pressure loss is 2% of the length loss.
Given: liquid - oil ρ = 1000kg / m3; υ = 0.1cm2 / s = 0.1 * 10-4m2 / s = 10 * 10-6m2 / s; Q = 50l / min = 0,00083m3 / s; Δ = 0.5mm = 0.0005m; d = 0.05m; H = 35m; l = 200m
