Water drips from a tap at the rate of 4 drops in every 3 seconds. Volume of one drop of `0.4 cm^(3)` If dripped water is collected in a cylinder vessel of height 7 cm and diametere is 8 cm In what time vessel be completely filled ? What is the volume of water collectd? How many such vessels will be completely in 3 hours in 40 minutes?

Water leaks out from an open tank through a hole of area 2mm^2 in the bottom. Suppose water is filled up to a height of 80 cm and the area of cross section of the tankis 0.4 m^2 . The pressure at the open surface and the hole are equal to the atmospheric pressure. Neglect the small velocity of the water near the open surface in the tank. a. Find the initial speed of water coming out of the hole. b. Findteh speed of water coming out when half of water has leaked out. c. Find the volume of water leaked out during a time interval dt after the height remained is h. Thus find the decrease in height dh in term of h and dt. d. From the result of part c. find the time required for half of the water to leak out.
