A non viscous liquid of constant density `10^(3) kg//m^(3)` flows in stream line motion along a vertical tube PQ of variable cross-section. Height of P and Q are 2m and 2.5m respectively. Area of tube at Q is equal to 3 times the area of tube at \'P\'. Then work done per unit volume by pressure as liquid flows from P and Q. Speed of liquid at \'P\' is `3 m//s`.
