A cylindrical tank 0.8m high and a diameter of 0.3m is partially filled with water to a certain depth. With the top part of the tank open, It is then rotated about its vertical axis at 240 rpm but no water spilled out. Determine the following: a. The depth (in meter) of the water in the tank. b. At what speed (in rpm) would the tank be rotated if 1.4 liters of water is spilled out c. At what speed (in rpm) would the tank be rotated so that the pressure at the center of the bottom of the tank be zero.

A cylindrical tank 0.8m high and a
diameter of 0.3m is partially filled with
water to a certain depth. With the top
part of the tank open, It is then rotated
about its vertical axis at 240 rpm but no
water spilled out.
Determine the following:
a. The depth (in meter) of the water in the
tank.
b. At what speed (in rpm) would the tank
be rotated if 1.4 liters of water is
spilled out
c. At what speed (in rpm) would the tank
be rotated so that the pressure at the
center of the bottom of the tank be
zero.
