Question

A pressure gage and a manometer are connected to a compressed air tank to measure its pressure. If the reading on the pressure gage is 11 kPa, determine the distance h between the two fluid levels of the water filled manometer. Assume the density of water is 1000 kg/m3 and the atmospheric pressure is 101 kPa.Quiz 3

Answer 1

h=1.122652m

Step-by-step explanation:

Assuming density of air = 1.2kg/m³

the differential pressure is given by:

`h^(i) =h((density of manometer)/(density of flowing air)-1)\\h^(i) =h((1000)/(1.2)-1)\\ h^(i)=832.33h...(1)\\\\but\\ h^(i) =(change in pressure)/(air density*g) \\\\h^(i) =(11*10^3)/(1.2*9.81)\\\\h^(i)= 934.42...(2)\\\\equating, \\\\934.42=832.33h\\\\h=1.122652m`
