A cylindrical tank 4.66 m in diameter is placed with its axis vertical and is partially filled with water. A spherical diving bell is then completely immersed in the tank causing the water level to rise 1.00 m . find the diameter of the diving bell. Solution rise in water level=1 m so rise in volume covered with water=pi*(D^2/4)*h D=diameter of cylinder=4.66 h=1m so rise in volume covered with water=17.0554 rise in volume covered with water= volume of sphere=(1/6)*pi*d^3=17.0554 d= diamere of sphere d=3.1937 so daimeter of bell=3.1937.
