m =2400kg/min=40kg/s
F=mg=40*10=400N
v=3m/s
Power=F.v=400.3=1200W
F=mg=40*10=400N
v=3m/s
Power=F.v=400.3=1200W

Per minute = 2400kg. that means per second = 2400/60 = 40kg/sec.
We know that Kinetic energy = 1/2 m * v * v
Power of pump = 1/2 * m * t * v * v
= 1/2 * 40kg/sec * 9m^2/sec^2
= 180W.
Hope this helps!
