a big fireplace can be approximated as 1.5 m3 of volume. its made of firebrick with properties ? 2600 kgm3 and c 950
why does turbulent flow distribution adhere more closely to the idealization of one dimensional flow than laminar flow?
an isolated chamber with rigid walls is divided into two equal compartments one containing steam at 10 bar and 370oc
hot exhaust gases carbon dioxide are cooled from 700 k to 300 k isobarically at 500 kpa. the cooling fluid is
saturated vapor at 8 mpa enters the turbine of a 100 mw net power vapor power plant. the pressure at the exit of the
Steam enters an adiabatic turbine at 6 MPa, 600°C, and 80 m/s, and leaves at 50 kPa, 100°C, and 140 m/s (T0 = 25°C, P0 = 100 kPa). If the power output of the turbine is 5 MW,
