Water flows through a very long 52 mm id (internal diameter) drawn copper pipe. the pipe is horizontal and has an internal roughness height of ε=0.0015 mm. the pressure drop along a 200m long section of the pipe is 100 kpa. find the friction factor f, reynolds number and average speed of the flow in the pipe. is the pipe flow laminar or turbulent?

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
