Question

A plastic straw, 20 cm long and 2 mm in diameter, is used to drink cold soda, approximated as water at 10°C (ρ = 1000 kg/m3, μ 1.307 x 10-3 kg/ms), at a rate of 3 cm3/s. (a) Calculate the head loss through the straw. (b) What is the pressure drop,AP, (in Pascal) if the flow is vertically up, or (c) horizontal?
