Question

A Newtonian liquid at 20 °C ($\rho$ = 900 kg/m$^3$, $\mu$ = 800 cP) flows through a straight pipe having a diameter of 4 cm and length of 20 m (laminar flow). Pressures at the inlet and outlet of the pipe are measured to be 750 and 100 kPa, respectively. If the pipe is inclined 20° to the horizontal plane and the flow is downward, calculate the volumetric flow rate.

Oil at 20°C is flowing steadily through a 6-cm-diameter and 33-m-long pipe. The pressures at the pipe inlet and outlet are measured to be 740 and 97.0 kPa, respectively, and the flow is expected to be laminar. The density and dynamic viscosity of oil at 20°C are ρ = 888 kg/m3 and μ = 0.800 kg/m·s, respectively.Determine the flow rate of oil through the pipe assuming fully developed flow and that the pipe is horizontal. The flow rate of oil through the pipe is is m3/s.

An incompressible liquid with a density of $900 \mathrm{kg} / \mathrm{m}^{3}$ and negligible viscosity flows steadily through a horizontal pipe of constant diameter. In a porous section of length $L=2 \mathrm{m}$ liquid is removed at a variable rate along the length so that the uniform axial velocity in the pipe is $u(x)=U e^{-x / L},$ where $U=20 \mathrm{m} / \mathrm{s} .$ Develop expressions for and plot the acceleration of a fluid particle along the centerline of the porous section and the pressure gradient along the centerline. Evaluate the outlet pressure if the pressure at the inlet to the porous section is $50 \mathrm{kPa}(\text { gage })$

00:01 Ok, so we have the formula delta p equal to 32 times mu times u bar times l over t square and we know that q is equal to a times u bar thus we get delta p equal to 32 times mu times q times l over a times t square and we have a equal to pi by 4 times t square thus we get delta p equal to 128 times mu times q times l over pi times t to the 4...
