AMK 10603 QUIZ 2

Element considered in major energy loses in enclosed pipeline:

• the enlargement of pipe

• the direction of water

• pipe surface roughness

• pipe area

High value of Reynold's number related to:

• high kinetic energy of water

• high elevation of pipe

• high velocity of fluid

• high viscosity of fluid

Based on the figure, the fluid element that will change if water flow from section 1 to section 2 are:

• The elevation

• The velocity

• The volume flow rate

• The pressure

Based on the figure, given diameter at section A is 250 mm and section B is 450 mm. If the water flow from A to B with flow rate of 0.4 m3/s, determine the velocity at B.

Based on the figure, if the desired velocity at the outlet pipe is 12 m/s, what is the minimum distance between the water surface and the center of the outlet pipe?
