Atank is half full of oil that has a density of 900 kg/m3. find the work w required to pump the oil out of the spout. (use 9.8 m/s2 for g. assume r = 3 m and h = 1 m.)

The work W required to pump the oir out of the spout is

Step-by-step explanation:

We are given the density of the oil, and we can calculate the volume of the oil as

because the tank is half full.

The we can calculate the oil mass as

Now, to calculate the work W necessary to pump the oil out, we have that

where m is already calculated, g is given in the problem, and h goes from 0m to 1m.

Finally we can calculate the work W:

Therefore

is the work required to pump the oil out of the spout.

do you mean add both of the equations together

because if you do the answer is 10x-5
