So, here in this question, first step is to calculate the absolute pressure to calculate the absolute pressure, the absolute pressure, pressure at the inlet, at the inlet, at the inlet and outlet of the pump, outlet of the pump.

Here, pressure of the inlet, which is p inlet is equals to the atmospheric pressure minus 150 millimeters of mercury into, into s g, g millimeters of mercury into 9 .8 meter per second square and this comes out to be 97 ,091 .5 pascals and the outlet pressure that is p outlet that is equals to 138 kilopascals plus 1 .2 meters that is the depth into 9 .8 meter per second square which is isolation due to gravity into 1200, sorry, 1200 kilograms per meter cube and that is equals to 152 ,112 pascals.

Now, second step is to calculate the density of brine, the density of brine, of brine.
01:47
Now, the density of water as we know, the density of water as we know is 1000 kilograms per meter cube...
