Awater pump with an available driven speed of 800 rpm is required to overcome a 1.83 m head while pumping 0.2 m3/s. use the specific speed and the table to decide the type of pump that is required. estimate the efficiency of the pump from the table and find the power supplied.

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
