Question

If density of a liquid is 20 g cm-1, height is 4 cm and gravitational field strength is 10 n kg-1, pressure of liquid is

Answer 1

Gases: If the fluid is a gas (and if the temperature remains constant), pressure is inversely proportional to volume for a given mass of gas, ie PV = C where C is a constant. ... Liquids: For most purposes liquids are incompressible so density does not change with pressure but at very high pressures density will increase.

Answer 2

Explanation:

pressure = height of column × density of the liquid × gravitational field strength. p = h \: \rho \: ... (Gravitational field strength, g, is 10 N/kg.).
