Question 3 [20 marks] Water (density p1000 kg/m2; dynamic viscosity 0.001 Pa-s) flows steadily through a horizontal, straight pipe with circular cross section of diameter D=0.2 m. The volumetric flow rate is 0.01 m°/s. Argue that this is turbulent flow. [4 marksl а. Pressure drop in the pipe is due to friction. The pressure drop per unit length can be written as Др 4f L with U the average velocity in the pipe and fthe friction factor. Given the pipe...

2.2 A 250 mm diameter pipe is 1500 m long. When the discharge is 0.095 m3/s in this pipe, the pressure drop between the ends of the pipe is measured as 98.06 kPa. The elevation at the end of the pipe is 10 m below its beginning. What type of flow is this? What is the equivalent sand-grain roughness of the pipe wall? What is the Hazen-Williams roughness coefficient? How much energy is dissipated by fluid friction during each hour...

1) A water fountain is to be installed at a remote location by attaching a cast iron pipe directly to a water main through which water is flowing. The entrance to the pipe is sharp-edged 15m (K-0.5), and the 15m long piping system involves three 90 bends without vanes (K1.1), a fully open gate valve (K.-0.2), and a fully open angle valve (K-5). If the diameter of the pipe is 2 em and the system is to...

In reaching her destination, a backpacker walks with an average velocity of 1.35 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.60 m/s, due west, turns around, and hikes with an average velocity of 0.480 m/s, due east. How far east did she walk?
