The p-type base of a crystalline silicon solar cell, 300μm wide, with an electron diffusion length of 400μm, has a perfectly passivated rear surface, with a zero surface recombination velocity. What is the probability that an electron generated near the back surface is collected at the junction ?
in a chocolate packing unit it takes a standard time of 0.01 hour to pack one carton box. the annual demand is 500000 carton boxes. assuming 1% scrap, calculate the number of men and machines required to complete the task if the packing unit is operational for 40 hours per week with 52 weeks in a year.
A 251.0 g/hr stream of liquid methyl alcohol, also called methanol, (CH3OH) at 9.00 atm and 28.0°C was held at constant pressure, vaporized and brought to 585.0°C. At what rate must heat be supplied to this system? Assume that methyl alcohol vapor behaves ideally for the temperature range and pressure given.
In an ideal rankine cycle, steam is generated at 4.1 MPa and 480 degrees C. The condenser is at 32 degrees C. Determine (a) The ideal pump work. (b) The cycle thermal efficiency, (c) For an engine with the same end states, determine its thermal efficiency, steam rate, and map, (d) considering the engine only, assume the brake engine efficiency to be 78%, the generator efficiency to be 92%, the steam flow rate 163,300 kg/hg; compute the output of the combined unit.
The density of copper is 3 3 8.93 10 / kg m . Calculate the number of free electrons per
cubic meter and hence their drift velocity when a current is flowing whose density is 21 / A cm . Take Avogadro’s number as 23 6.022 10 / atoms mole and the molar mass of cupper is 63.55g.
