6. The fill line for a tank swages up from 8" Schedule 40 pipe to 16" Schedule 40 pipe. The velocity entering the tank must be limited to 3 ft/s to avoid a static charge build up in the tank. A) What is the maximum velocity allowed in the 8" section of pipe? B) What is the maximum volumetric flow rate entering the tank?

c) Water flows through an 8-inch steel pipe at an average velocity of 6 ft/s. Downstream the pipe divides into an 8 inch main and 2 inch bypass. The equivalent length of the bypass is 22 ft; length of the 8-inch pipe in the bypassed section is 16 ft. Neglecting entrance and exit losses. What fraction of the total water flow passes through the bypass?

4a) A Ship must discharge a total of 2200 cubic meters Sea water ballast Within 6 hours. Using S SNAME reccomended fluid Velocity, size and Select the appropriate scha 40 Steel pipe. What is the actual velocity? total head is 6) Calculate the power to drive the ballast pump in part a) if the 65m. What power would be required the ship was in fresh water? (Sea water SG: 1.025, freshwater : 17 1)

The rest of the questions are thus: 4) Calculate the air temperature and pressure in the pump at the end of the following expansion stroke, just before the piston uncovers the orifice (orifice dimensions are neglectable).5) Calculate the mass and temperature of air in the pump (i.e. the cylinder andconnecting pipe) after the orifice has been exposed and the pressure has risen to atmospheric pressure (bottle valve is now closed).7) Calculate the piston position and the air temperature in the pump during the next compression stroke at the time when the valve to the gas bottle opens again.8) Calculate the pressure in the bottle when no more air can be transferred by the pump. (This will be after an undetermined number of pumping cycles).
