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.

An inclined pipe of 4-inch ID is used to transport a viscous oil from one open-top container A to another open-top container B. The specific gravity of the oil is 0.9 and the viscosity of the oil is 20 cp. The length of the pipe is 100 ft. Oil levels in these two containers are shallow and the inlet and outlet pressures across the tube can be assumed to be identical – both 1 atm. What is the angle needed to maintain a flow rate of oil of 1 cuft / second? The levels of oil in A and B do not change – oil is continually added to A at the rate of 1 cuft / second and is continuously removed from B at the same rate. A

Sheet 1 Page 1 of 2 Q1/ An orifice meter is to be calibrated for the measurement of the flow rate of a stream of liquid acetone. The differential manometer fluid has a specific gravity of 1.10. The calibration is accomplished by connecting the orifice meter in series with a rotameter that has previously been calibrated for acetone, adjusting a valve to set the flow rate, and recording the flow rate (determined from the rotameter reading and the rotameter calibration curve) and the differential manometer reading, h. The procedure is repeated for several valve settings to generate an orifice meter calibration curve of flow rate versus h. The following data are taken.
