Part A - Laminar flow Water flows through a circular pipe with e = 0.15 mm , D = 15 cm , and L = 30 m at a rate of Q = 91 cm3/s. The viscosity of water is vw = 1x10-2 cm²/s. What is the head loss due to friction? Express your answer in m to three significant figures. ► View Available Hint(s) ΤΙ ΑΣφ JT vec ? hL = = m Submit
Part B - Moody diagram Water flows through a circular pipe with € = 4.5x10-2 mm and D=9 cm at a rate of Q = 90 L/s. The viscosity of water is Vw = 1x10-2 cm²/s. What is the friction factor?
