$1\mathrm{.}5$ A purnp with an available driven speed of $800$ rpm is required to overcome a $1\mathrm{.}83$ m head

while pumping $0\mathrm{.}2\frac{m^3}{s}.$ What type of pump is required and what power is required?

$1\mathrm{.}6$ A reservoir has a head of $40$ m and a channel leading from the reservoir permits a flow rate of

$34\frac{m^3}{s}.$ If the rotational speed of the rotor is $150$ rpm $,$ what is the most suitable type of turbine to

use?
