Hgalf way The empirical expression for the velocity of water, according to the Hazen-Williams formula, is given in SI units as 0.63 0.54 V C R S  0.849 hw h where H is hydraulic radius and S is head loss per unit length (hL/L). Consider a 1-m wide, 1-m high square concrete conduit filled for 50% with water. What is the roughness coefficient Chw for flow at a rate Q=2 m3 /s in a 500-m long conduit with an elevation difference of 5 m?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

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
