Compute the work done against gravity by a pump that discharges 600liters of fuel oil into a tank 20m above the pump intake. One cubic centimeter of fuel oil has a mass of 0.82 grams. One liter is 1000 cm3

What do you think the answer is and how would you go about working it? We do not do your assignment for you, but we can help you once you show us what you have so far.

The only tricky part is calculating the mass of 600 L of fuel oil. Then W=mgh. Show us your work and we'll be glad to check it for you.
