$($solve it for fluid mechanics $)$ Water $($absolute viscosity is $0\mathrm{.}001$kg$//$m$.$s$,$density is $1\mathrm{.}0$kg$//$m$^(3))$ is to flow from reservoir A to reservoir B through a pipe of length $20$ m and diameter $100$ mm at a rate of Q$=0\mathrm{.}005$m$^(3)//$s as shown in Fig. Prob. $7.$ The system contains a sharp$-$edged entrance, six regular threaded $90^($@$)$ elbows and exit which loss coefficients are $0\mathrm{.}5,1\mathrm{.}5$ and $1\mathrm{.}0$ respectively. please $(20$Points$)$

determine its laminar or turbulent flow? find the total loss from tank B to tank A$.$ find the minor loss from tank B to tank A find the major loss from tank B to tank A find the friction factor of the pipe If it's a cast$-$iron pipe, do you have another way to find out the friction factor, please give a brief description of the procedure. If we need to lift the water from reservoir B to reservoir A$,$ a pump must be installed, please calculate the required output power of water pump If the water pump efficiency is $70\%,$ please calculate the required power of water pump.
