1.	A 20-0 litre bucket can be filled with water using a water hose 3-00 cm in diameter in 2 minutes. Calculate the speed with which the water leaves the hose.
Answer» Solution : Volume of water FLOWING PER second `= ( 20 xx 10 ^(-3) m^(3))/( 2 xx 60 s) ` ` "" = 1.67 xx 10 ^(-4) m^(3)//s` Radius of the hose ` = r= 1.5 cm = 0.015 m` Speed of water flow `= v = ? ` ` "" AV= 1.67 xx 10 ^(-4)` `"" v= (1.67 xx 10 ^(-4))/(pi r ^(2)) = (1.67 xx 10 ^(-4))/( 3.14 xx (0.015)^(2))` `"" v= 0.24 m//s`
