Q1

The sphere of an ancient water clock jug is such that water level descends at a constant rate at all times. If the water level falls by 4 cm every hour, determine the shape of the jar, i.e., specify x as a function of y. The radius of drain hole is 2 mm and can be assumed to be very small compared to x.

                                                                       

Q2

A rectangular tank of height 10 m filled with water, is placed near the bottom of a plane inclined at an angle 30o with horizontal.
