Question

A diver is 15m below the surface of a liquid density 1050kg/m3.Calculate the total pressure on the diver given that atmospheric pressure in the region is 70cmHg.(take density of mercury to be 13600kg/m3 and g=10N/kg)

Answer 1

Step-by-step explanation:

pressure due to fluid column = hdg where h is height of column , d is density of fluid , g is acceleration due to gravity .

Total pressure on the diver = atmospheric pressure + pressure due to water

= .70 x 13600 x 10 + 15 x 1050 x 10

= 95200 + 157500

= 252700 Pa

= 2.527 x 10⁵ Pa .
