The flywheel of a steam engine runs with a constant angular speed of 405 rev/min (in the counterclockwise direction). When steam is shut off, the friction of the bearings stops the wheel in 1.9 h.
What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown?

Herbivores, carnivores, and omnivores are all types a. decomposers b. producers c. consumers d. biomes

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.

Find the mass by adding the numbers from the three sliders
