Calculate the reynolds number for an oil gusher that shoots crude oil 25.0 m into the air through a pipe with a 0.100-m diameter. the vertical pipe is 50 m long. take the density of the oil to be 900 kg/m3 and its viscosity to be 1.00 (n/m2)·s (or 1.00 pa·s).

Explanation:

Given:

vertical height of oil coming out of pipe,

diameter of pipe,

length of pipe,

density of oil,

viscosity of oil,

Now, since the oil is being shot verically upwards it will have some initial velocity and will have zero final velocity at the top.

Using the equation of motion:

where:

v = final velocity

u = initial velocity

Putting the respective values:

For Reynold's no. we have the relation as:

no link

explanation:

it becomes positively charged by charging it
