A Carnot heat engine receives heat from a reservoir at 900oC at a rate of 800 kJ/min and rejects the waste heat to the ambient a
ir at 27oC. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5oC and transfers it to the same ambient air at 27oC. Determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air.
if a small gear is making 5 rpm turning a big gear thats making 1 rpm the bug gear is making lots of torque but if its going the opposite way its much harder to turn the big gear 1 rpm just to make the little gear do 5 rpm and it makes way less torque if thre both the same size there ging to stay the same speed
Advertisements. A Switch is a device that makes or breaks a circuit or a contact. As well, it can convert an analog data into digital data.
Data switch :-
A switch box that routes an input signal to an output line; for example, to connect two computers to one printer. Manual data switches have dials or buttons. Automatic switches test for signals on the input lines and provide first-come, first-served switching.
