A liquid with a relative density of 1.82 is being drawn from a storage tank through a 3-inch pipe using a pump. The flow rate of the liquid through the 3-inch pipe is 0.9 m/s. The pump is discharging the liquid into the tank above through a 2-inch pipe. The end of the discharge pipe is 15 m above the feed tank and the system has a frictional head loss of 3 m. Given that the efficiency of the pump is 70%, calculate the motor power of the pump in kW.

Transcribed Image Text:SORU 3. Bağıl yoğunluğu 1.82 olan bir sıvı,
depolama tankından 3-inçlik bir boru ile
pompa kullanılarak çekilmektedir. Sıvının 3-
inçlik borudan akış hızı 0.9 m/s'dir. Pompa
Sıvıyı yukarıdaki tanka 2-inçlik bir boru ile
boşaltmaktadır. Boşaltma borusunun ucu
besleme tankından 15 m yukarıdadır ve
sistemde sürtünme yük kaybı 3 m'dir.
Pompanın verimi %70 olduğuna göre,
pompanın motor gücünü kW cinsinden
hesaplayınız.
