Question
1) what is the pressure difference (psi) if a room temperature manometer reads 50 cm height of water?2). What is the pressure difference (psi) if room temperature manometer reads 80 cm height of mercury?
3) a room temperature tank filled with water is pressuriZed at the top with nitrogen at 30 psig. What is the pressure (psig) at the bottom if the tank is 200 cm deep?
4) a room temperature tank filled with glycerin is pressurized at the top with nitrogen at 24 psig. What is the pressure (psig) qt the bottom if the tank is 100 cm deep? 1) what is the pressure difference (psi) if a room temperature manometer reads 50 cm height of water?

Explanation / Answer
1.
density of water p=1000 kg/m3
Pressure difference of manometer
dP=pgh=1000*9.81*0.5
dP=4905 pascals
1 pascal=0.000145038 psi
dP=4905*0.000145038
dP=0.7114 psi
2.
Pressure difference of manometer
dP=pgh=1000*9.81*0.8
dP=7848 pascals
1 pascal=0.000145038 psi
dP=7848*0.000145038
dP=1.1383 psi
