Question

A through shaped tank is located 3 meters underground (The top of the tank is 3 meters away from ground level.) The dimensions of the tank are: height h = 5 meters, length c = 10 meters, base width a = 4 meters and top width b = 8 meters. If the tank is completely full, find the work done in pumping all the water out of the tank to ground level.

Answer 1

900kJ

Step-by-step explanation:

Work done hereis lifting that water mass on to the surface level

v = volume of the tank

d= density of water (1000kg/m3)

g = gravotational acceleration

workdone=Weight * distance

= (v*d*g)*distance

=
`=(((8+4)/(2) )*5*10)*1000*10*3\\=900000J\\=900kJ`
