Heya i have this question over here... i have done the first part of it(adsbygoogle = window.adsbygoogle || []).push({});

An open tank weighing 1000 N contains 0.6 m3 of water. Calculate the force required to support the system against gravity.

Answer is 6886 .. the calculation i have done is convert the 0.6 meter cubic into m.liters and then convert it to Kilograms after that i multiply it with Gravity to give me 5886 and then i add the weight of the tank on it to give me the final answer

If a streamlined orifice of 120 mm diameter, discharging a flow of 90.5 kg/s, is fitted in the floor of the tank, what supporting force will now be required? Assume that the orifice discharges to atmosphere, and that the water level in the tank remains steady. Ans:6156

HERE where i am stuck i dont know what to do after this step so please help me thanks
