0.1kg/cm^2 = 1m,

Pressure of 5m water = pressure of 5m* sp.gravity,
Or, = 2.5 * 0.8,= 2

Therefore
(1+2)= 3m.

Pa = 0.1 kg/cm2 = 1000 kg/m2.

Poil = 800*2.5 = 2000 kg/m2.

Total = 3000 kg/m2 = 3000/1000 = 3 meters of water.

How (total pressure/atm pressure) is equal to the pressure head of water?

Please explain anyone.

Thanks.

Don't understand clearly.

Anyone, please solve it by standard formula with step by step with meaning.

How do you calculate the pressure at the given height? Please explain me.

Nikku said:   1 decade ago
Pressure head in terms of water = 2.5/0.8 = 3.1m.

Yes, your answer is correct. Thank you @Dipesh.

Total pressure = ((.1*10^4)/1000)+(.8*2.5) = 3.

1 kg/m2 = 1000kg/cm2 this are correct.

Simply P = density * gh.
