Calculate the pressure in cm H2O exerted in the closed end of an apparatus if the atmospheric pressure is 720.0 torr and the height of the water coloumn is 22.3cm.

Expert Solution

atmospheric pressure = 720.0 torr

height of the water coloumn = 22.3cm.= 0.223 m

1 torr = 133.3 pa

atmospheric pressure = 720.0 torr = 95976 Pa

pressure exerted = atmospheric pressure + pressure head

= Po + gh

= 95976 + (1000 x 9.8 x 0.223)

= 98161.4 Pa

1 Pa = 0.0101972 cm H2O

98161.4 Pa = 98161.4 x 0.0101972

= 1000.97 cm H2O

pressure exerted = 1000.97 cm H2O
