Question 2 - 20 marks a (a) Water at 15 C (p = 999.1 kg/m' and u = 1.138 X 10 kg/m.s) is flowing steadily in a 30 m long and 4 cm diameter horizontal pipe made of stainless steel at a rate of 8 L/s. Please use Moody Chart to determine: i. the pressure drop ii. the head loss, and iii. the pumping power requirement to overcome this pressure drop (12 marks) (b) Refer to Question 2(a). Please use SE Haaland method to determine : i. the pressure drop the head loss, and the pumping power requirement to overcome this pressure drop ii.
