(b)
cast iron pipe when water at 15°C flows at 1.5 m/s. Assume that the pipe has a roughness of
0.244 mm. Viscosity and density of water are 1 x 10 Pa s and 1000 kg/m' respectively.
Determine the energy loss in 300 m of new, uncoated 30.5 cm inside diameter
fe) What are the conditions that transform the mechanical energy equation into the
Bernoulli equation? State the energy balance cquation as the Bernoulli equation.
(d) The tank below is cylindrical with a diameter of 10 m. The outlet is a cylindrical
frictionless nozzle, with a diameter 1 m. The top of the tank is open to the atmosphere. When
the level in the tank is 10 m above the centerline of the outlet, how fast is the level in the tank
falling?
