Two air tanks are connected by two parallel circular tubes, one having an inside diameter of 1 cm and the other an inside diameter of 0.5 cm. The tubes are 2 m long. One of the tanks has a higher pressure than the other, and air flows through the two tubes at a combined rate of 0.00013 kg/s. The air is initially at 1 atm pressure and 16°C. Assuming that fluid properties remain constant and that the entrance and exit pressure losses are negligible, calculate the pressure differences between the two tanks (assume laminar flow). Assume fully developed flow (15 points). Discuss your answers if the flow entry length was taken into consideration (10 points).
