Question

An IV bag is situated 1m above a patient and the density of the fluid in the bad is 1020kg/m3. If the cross sectional area of the needle is 1x10^-8 m2, what will be the flow rate of the fluid into the patient? Assume the IV bag is collapsible, so the external pressure at the bag is just atmospheric pressure and that the gauge pressure at the patients vein is 1.30x10^3 Pa.
