Abarometer contains mercury with a density of 13600 kg/m3. atmospheric conditions are 95.8 kpa and 20 °c at 20 °c, the vapor pressure of the mercury is 0.000173 kpa. the column of mercury will rise to a height of most nearly. select one: a)- 0.38 m b)- 0.82 m c)- 0.48 m d)- 0.72 m
Areaction-bonded silicon nitride ceramic has a strength of 250 mpa and a fracture toughness of 3.4 mpa(m)^1/2, what is the largest-sized internal flaw that this material can support without fracturing? (use y -1 in the fracture-toughness equation.)
An ideal vapour-compression heat pump cycle provides a heating rate of 12btu/s. the working fluid, refrigerant 134a, enters the compressor as a saturated vapor at 40 psi and exits the condenser as a saturated liquid at 160 psi. determine (a) the mass flow rate of the working fluid in lb/min (b) the compressor power in btu/min. (c) the coefficient of performance.
