Agarden hose discharges water at the rate of 15 m/s. if the nozzle is held at ground level and directed θ = 30° from the ground, determine the maximum height reached by the water and the horizontal distance from the nozzle to where the water strikes the ground.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
