Design a cast iron (kd=8*10‐4 ft) pressurized system (pipe diameter) that would convey water at 2 ft3/s from two elevated tanks separated 200 ft long. The difference in water surface elevation between the tanks is 20 ft and the kinematic viscosity is 1.217*10‐5 ft2/s. Along the system the entrance loss and the exit loss have a KL of 0.5 and 1, respectively. Two 90 degrees bends are present (KL=3) and a global valve (KL=10) is also installed along the system.

The large blood vessel leading from the human heart, the aorta, has an inside diameter of 1.0 cm and a length of 40 cm. The flowing blood (SG = 1.06) has a viscosity of 3.5 CP and an average velocity of 60 cm/s. Find the pressure drop across the aorta, if it is (a) horizontal, (b) vertical with upward flow, and (c) vertical with downward flow.

A conventional, rectangular flocculation basin is 38 ft. wide, 90 ft. long and 16 ft. deep. The flow through the basin is 24 mgd and the water horsepower input by the reel type paddles is 15 hp. The dynamic viscosity of water is 2.73 E -5 lb/sec/ft2 at 50 degrees Fahrenheit. The flocculation basin in above is followed by four sedimentation basins which operate in parallel.   Each basin is 30 ft. wide, 240 ft. long and has an effective settling...

There is a gas cylinder filled with oxygen in front of you. It is 1.5 meters tall and 30 cm in diameter. The oxygen within the culinder has dropped to a gauge pressure of 2.52x10^6 Pa at a temperature of 20 C. This pressure is insufficient to ventilate a patient in respiratory distress. Youdo not have another oxygen cylinder present, and without oxygen the patient will die. a. To maintain minimal ventilation, the pressure must be raised to a gauge...
