If not given handwritten I'll dislike for sure so better skip if not handwritten
Given that flow rate of the water =120 litres/sec, calculate the magnitude and direction of the deflection h of the differential mercury manometer. Neglect all losses in the pipe.
Calculate the minimal head of the pump required to pump 1 m³ of water per second to the height 10 m trough a pipe with cross sectional area 0.1 m². Assume constant friction coefficient f = 0.04 and neglect all losses in fittings. The pump head is the gravity head plus losses and so it can be found?
