4. The drum has a hole in the center of its lid and contains kerosene to a level of 400 mm when angular velocity is 0. If the drum is placed on the platform and it attains an angular velocity of 12 rad/s, determine the resultant force the kerosene exerts on the lid. 300 mm 200 mm 400 mm

My question is in this problem: A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe is taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. In order to drain the tank faster, a pump is installed near the tank exit as in fig . Determine how much pump power input is necessary to establish an average water velocity of 4 m/s when the tank is full at z = 2 m. Also, assuming the discharge velocity to remain constant, estimate the time required to drain the tank. Someone suggests that it makes no difference whether the pump is located at the beginning or at the end of the pipe, and that the performance will be the same in either case, but another person argues that placing the pump near the end of the pipe may cause cavitation. The water…

Gasoline (T=50 degrees F) is pumped from the gas tank of an automobile to the carburetor through a 1/4 in fuel line of drawn tubing 10 ft long. The line has five 90 degree smooth bends with an r/d of 6. The gasoline discharges through a 1/32 in jet in the carburetor to a pressure of 14 psia. The pressure in the tank is 14.7 psia. The pump is 80% efficient. What power must be supplied to the pump if the automobile is consuming fuel at a rate of 0.12 gpm. S=0.68, 2ft Pump 1/4 in line (ID) Carburetor tul
