You are drinking water through a straw of length 16cm and diameter 4mm at a flow rate of 1mL/s. You can assume density of water =999Kg/m, dynamic viscosity of water = 0.001Pas and acceleration due to gravity 9.81m/s. a) Considering laminar flow, what is the head loss hL through the straw? Provide your answer to 3 decimal places. hL = b) Consider that the straw is positioned vertically, what is the pressure gradient along the straw in vertical direction deltap/L. Provide your answer to 3 decimal places. deltap/L: kPa/m. = m.
