a conical tank with height 10 and radius 2 is filled to the top woth a liquid weighing 15 n/m^3 how much work is spent pumping all of the liquid out of the tank through the top

A cylinderis fitted with a piston beneath which is a spring, as in the attachment.  The cylinder is open to the air at the top.  The sprink constant is 4300 N/m. The piston has negligible mass and a radius of 0.032.  When the air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress? How much work does the atmospheric pressure do in compressing the spring.

4) The turbine extracts 0 hp from the water flowing through it. The pipe with diameter of 1 ft and length of 300 ft is assumed to have a friction factor of 0 02. Minor losses are negligible. Determine flowrate through the pipe and turbine? Head losses is h₁ = 85 ft ▼ Imad ti EBOOK (1) 1 = 90 ft 300-ft-long, 1-ft-diameter pipe f = 0.02 Turbine (2) Free jet 42 = 0

The tank shown contains water to a level1 meter from the top. The tank is 3-meter wide at the top, and it has a depth of 3 meter and a length of 8 meter. Find the work required to pump all the water out of the spout, 2 meter above the top of the tank (the density of p = 1000; acceleration due to gravity at the earth's surface is 9.8) 14. kg and the m3 m TA十al
