The pump can generate a pressure of 2.3x107 pa
so,
a radius of 0.041 m
so,
a stroke lasting 29 s, the piston moves 0.57 m
so,
Firstly, we will find area
now, we can use power formula
F=pA
W=Fh
so, W=pAh
we can plug it
now, we can plug values
now, we can simplify it
Power=2386.92414 watt.........Answer
