Acoal-burning steam power plant produces a net power of 350 mw with an overall thermal efficiency 12 kg air/kg fuel. the heating value of the coal is 30,500 kj/kg. determine (a) the amount of coal consumed during a 24-hour period mcoal and (b) the rate of air flowing through the furnace.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
