In this question, the density of oil is given as 850 kg per meter cube.
00:08
And the viscosity of the oil is 0 .0062 meter cube per second.
00:20
Now, in this question, we calculate the rate of flow of oil.
00:25
And assuming, neglect all minor losses.
00:34
So first of all we calculating the pressure drop in the oil.
00:42
So this is row g h.
00:45
The density of the oil is 850.
00:48
Accolation due to gravity is 9 .81 and the height you can see in the picture.
00:53
This is 4 meter.
00:56
So after solving this equation we get the pressure drop is 33 .354 times 10 power 3 pascal.
01:07
Now we calculate the dynamic viscosity.
01:09
That is equal to density of the oil times pneumatic viscosity...
