Question: An intravenous (IV) system is supplying saline solution to a patient at the rate of 0.12 cm3/s through a needle of radius 0.2 mm and

An intravenous (IV) system is supplying saline solution to a patient at the rate of 0.12 cm3/s through a needle of radius 0.2 mm and length 6.17 cm. What gauge pressure (in Pa) is needed at the entrance of the needle to cause this flow? Assume that the viscosity of the saline solution to be the same as that of water, n = 1.0*10- Pa-s, and that the gauge pressure of the blood in the vein is 1500 Pa. Enter an integer. Question 2 2 pts A Venturi tube may be used as a fluid flow meter. If the fluid flow rate in m3/s is 1.7* 10-3 and the radius R1 = 2.4 *10-2 m of the inlet tube is 2.4 times the radius R2 of the outlet tube, and the fluid is water (p = 1000 kg/m3), find the pressure difference P1 - P2 in units of kPa. Enter a number with one digit behind the decimal point
