¿force of friction (in N) exerted by the spigot on the plug?
As a means of fire protection, a small town has a large cylindrical tank with an open top. Water exits the tank through a 6.30 cm diameter hose which ends with a 2.05 cm diameter spigot. If a plug is inserted into the spigot and the water level in the tank is kept 7.50 m above the spigot, determine the following.
force of friction (in N) exerted by the spigot on the plug
mass of water (in kg) that will flow through the spigot in 2.00 hr, if the plug is removed
gauge pressure (in Pa) of the flowing water in the hose just behind the spigot
