1.	per hour through a pipe of diameter Irectangular tank which is 50 m long and 44 m wide. Find the time in which the level ofwater in the tank will rise by 21 cm.
Answer» In cylinder,r=7cm=0.7ml=15km=15000m In tank,l=50mb=44mh=0.21m Vol.of water in tank=lbh =50440.21 =462m³ Height of cylindrical pipe=Vol. /πr² =462/(0.07)²(22/7) =462/0.0154 =30000m Time = 30000/15000 = 2 hours

Answer»

In cylinder,r=7cm=0.7ml=15km=15000m

In tank,l=50mb=44mh=0.21m

Vol.of water in tank=lbh =50*44*0.21 =462m³

Height of cylindrical pipe=Vol. /πr² =462/(0.07)²(22/7) =462/0.0154 =30000m

Time = 30000/15000 = 2 hours
