Water at 60 °F flows through a 6-in. schedule 40 pipe (D=6.065 in.), through a reducer, and then through a 4-in. schedule 40 pipe ( Dro = 4.026 in) at a rate of 80 gal/min. The pressure is 40 psig at the reducer inlet and 34 psig at the reducer outlet. Determine the force of the water on the reducer. Note: A reference other than this textbook will readily provide the actual inside diameter of the schedule 40 pipes you will need to answer this question.

Need detailed solution. 4 decimal places. Oil with a specific gravity of 0.82 is flowing in a pipe under the condition below. If the total head loss from point 1 to point 2 is 3 ft, find the pressure at point 2 in psi. *cfs = cubic ft per sec

On average, you inhale approximately 1 L of air every 2 seconds. The pressure difference between the outside air and your chest cavity creates this flow. The air flows through your trachea which has a radius of 0.005m and a length of 0.12m. Do not ignore the viscosity of air in this problem. a. What is the velocity of the air moving through the trachea? b. Is this flow laminar or turbulent? Support your answer with calculations. c. What is the pressure in your chest cavity required to create this flow? Assume the outside air has a pressure of 1 atm.
