In an adjustable nozzle for a garden hose, a cylindrical plug is aligned along the axis of the hose and can be inserted into the hose opening. The purpose of the plug is to allow the water to escape around the plug and change the speed of the water leaving the hose. The speed of the water passing around the plug is to be 5 times as large as the speed of the water before it encounters the plug. Find the ratio of the plug radius to the inside hose radius. rplug / rhose =

Hot water with a density of 980 kg/m3 flows through a 51.2 mm diameter round pipe at 1.25 m/s.  What is the mass flow rate (in kg/s) of the water  How many significant figures should be used in the final answer?

A garden hose having with an internal diameter of 1.7 cm is connected to a (stationary) lawn sprinkler that consists merely of an container with 23 holes, each 0.20 cm in diameter. If the water in the hose has a speed of 0.93 m/s, at what speed does it leave the sprinkler holes? m/s

A tank in the form of a right-circular cylinder of radius 0.4 m and height 3 m is standing on end. When water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of the water leaving the tank per second to CA,√2gh. If the tank is initially full of water, and water leaks from a circular hole of radius 17.5 mm at its bottom, determine a differential equation for the height h of the water at time t. Ignore friction and contraction of water at the hole, that is let c = 1. (Assume the acceleration due to gravity g is 9.8 m/s². Round your numeric value to five decimal places.) dh dt = eBook -3 8.47392 10 3 √h
