Aconcrete box culvert with manning’s roughness coefficient n = 0.015 and a rounded entrance (ke = 0.2) is to be designed to carry the design flow of 9.8 m3 /s. the culvert slope is 0.3% and the length is 38.0 m. if the maximum-allowable headwater level is 2.8 m above the culvert invert, determine the size of the box culvert with free-outlet conditions and verify the flow type

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
