You work as a project engineer at a water supply company for residential area. You are asked to evaluate the operation of a Taco brand pump Model $4013$ that rotates at $1160$ rpm$.$ Basically, the pump supply water at a temperature of $20$oC from Reservoir Tank $1$ and sends it to Reservoir Tank $2$ through a $90$ mm diameter pipe, as shown in Figure Q$2($a$).$ The water level in Reservoir Tank $1$ is $2$m and in Reservoir Tank $2$ is $7$m measured from the center$-$line of the pump. The horizontal distance between Tank $1$ to Tank $2$ is $25$ m$.$ You are aiming for an operating flow rate of $450$ gallons per minute $(1$ gallon per minute $=6\mathrm{.}31$X$10-5$ m$3/$s$).$ The pump performance curves using different impeller sizes are given in Figure Q$2($b$).$

$$Select a suitable piping material for the operation of the system and clearly state your reason for such selection.

Design all pipe connections, appropriate valves from Reservoir Tank $1$ to Tank $2$ through the pump. Refer to Figure Q$2($a$)$ as a guide but your design is not limited to that Figure. Evaluate and clearly describe the minor head losses considered in your system.

Evaluate the total head required for pump Anda berkerja sebagai jurutera projek di syarikat pengedalian air untuk kawasan perumahan. Anda diminta untuk menilai operasi pam berienama Taco Model $4013$ yang berputar pada $1160$ rpm $.$ Pada asasnya, pam tersebut mengepam air pada suhu $\backslash (20^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ dari Tangki Takungan $1$ dan menghantarnya ke Tangki Takungan $2$ melalui paip diameter $90$ mm $,$ sebagaimana ditunjukkan dalam Rajah S$2($a$).$ Paras air di Tangki Takungan $1$ ialah $2$ m dan di Tangki Takungan $2$ ialah $7$ m diukur dari garisan$-$tengah pam. Jarak mendatar diantara Tangki $1$ ke Tangki $2$ adalah $25$ m $.$ Anda menyasarkan kadar alir operasi $450$ gelen seminit $(1$ gelen seminit $\backslash (=6\mathrm{.}31\backslash$times $10^\{-5\}\backslash$mathrm$\{$~m$\}^\{3\}/\backslash$mathrm$\{$s$\}\backslash )).$ Keluk prestasi pam menggunakan saiz pendesak yang berbeza diberikan dalam Rajah S$2($b$).$
