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.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
