1) A pipe of diameter 10 cm, with an orifice of diameter 1.25 cm points straight up, and the stream of orange juice it is delivering reaches a height of 20 m. Find the flow velocity in the hose and the volume of orange juice flowing per unit time, neglecting the effect of air resistance on the stream.
3) Blood, during transfusion, flows from a bottle through a needle that is 3.5 cm long and has an inside diameter of 0.60 mm. How high above the needle must the bottle be held in order to transfuse 0.50 L of blood in 40 min? The density of whole blood is 1050 kg/m3 and the viscosity of whole blood is 2.7 X 103 N.s/ m2. Assume the patient’s blood is nearly at atmospheric pressure.
4) A 1.3-m length of horizontal pipe has a radius of 6.4 X 10-3m. Water flows with a volume flow rate of 9.0 X 10-3 m3/s out of the right end of the pipe and into the air. What is the pressure in the flowing water at the left end of the pipe if the water behaves as (a) an ideal fluid and (b) a viscous fluid (the viscosity of water is 1.00 X 10-3 Pa.s)
