Pump delivers $0\mathrm{.}314\frac{m^3}{s}$ flow of water at the temperature of $20C$ and

the intake pipe diameter is $30$ cm as shown in Figure $3.$ The pump

operates at $1470$ rpm $.$ The length of the pipe from the pump to the lower

tank is $30$ m $.$ The equivalent sand grain roughness, $=0\mathrm{.}046mm.$

Kinematic viscosity, Check whether there will be cavitation for these

conditions. Assume, minor loss coefficients, $20C$ is $2\mathrm{.}34$ kPa $.$ The

specific weight of water $20C$ is $9\mathrm{.}789k\frac{N}{m^3}.$
