Q 1 very important - The pressure in a water pipe on the ground floor of abuilding is 80000 Pa whereas on the third floor it is 10000 Pa Find the height of the third floor Take g=10m per secondsquare Calculate the hydrostatic pressure exerted by water at the bottom of a beaker ? Pleaaaaaaase answer this que after tommorrow is my exam hurryyyyyyyyyyyyyyyy

Dear Student,

Pressure at ground floor=80000 PaPressure at third floor=10000PaDifference in pressure of water at ground floor and third floor, P=80000-10000Difference in pressure of water at ground floor and third floor, P=70000 PaLet h be the height of third floor
Pressure of water due to height, P=hdg70000=h×1000×10h=7 m

Height of water column, h=45 cm=0
45 mg=9
