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?

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.
