Answer 1

Answer:

Power= mgh/ Time

Keeping the value, in SI units

2000 watt = (mx 9.81×10 )/ 60

m= mass of water = 1223.2415 kgs

If you wish to convert it in litres then,

Density= Mass / Volume

Or, Volume= Mass/ Density

Volume 1223.2415/ 1000

Volume = 1.2232415 meter cube

And if you want in litres, then

1 meter cube = 1000 litres

So, Volume 1.2232415 x 1000 litres

= 1223.2415 litres
