Acoal-burning steam power plant produces a net power of 300 mw with an overall thermal efficiency of 33 percent. the actual gravimetric air–fuel ratio in the furnace is calculated to be 12 kg air/kg fuel. the heating value of the coal is 28,000 kj/kg. determine the amount of coal consumed during a 24-hour period. (you must provide an answer before moving to the next part.) the amount of coal consumed is kg/s.

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.

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
