In this term paper, I have compared Rankine cycle with Carnot cycle, I have given the idea of the application of Rankine cycle in steam power plants and the methods to increase the efficiency of the Rankine cycle. ... EFFICIENCY OF RANKINE CYCLE Heat supplied QH =m (h2-h1) Heat removed QL= m(h3-h4) hth/r =1-QL/QH= (h2-h1)/(h3-h4) REASONS FOR THE INEFFICIENCY OF THE RANKINE CYCLE 1) Frictional losses in pumping the working fluid. 2) Heat losses from high components in the system to the environment. 3) Reduced condenser performance because of air, leakage into the sub-atm...

INVESTIGATION OF THE FACTORS AFFECTING THE TIME PERIOD OF A SIMPLE PENDULUM I will begin with an explanation of motions and Galileo's discovery of motion under gravity: Galileo's insight was that all bodies fall equally fast in a gravitational field. "Falling in space,"" means simply following the orbit under gravity. There is no need for this "falling" to be straight down since there is no up, down or any point of reference in space. Gravity can be cancelled in this way by free fall because the effects of a gravitational field are just like those of acceleration. Indeed if you...

These basic food components are broken down in our cells to release the stored energy, which allows human movement. ... The Oxidative system Each of the above method is good at supplying energy for the everyday bodily demands whether its completing a marathon or a batsmen completing a stroke in cricket it allows us to cope with different situations. ... Aerobic metabolism is the primary method of energy production during pro-longed exercise and for cricketers this means being in the field maybe for hours. ...

In addition to manufacturing many of its own charge controllers and some of its invertors, Cuba is assembling components from imported cells and hopes that in the future it will manufacture its own cells as well. ... It is an obvious priority to improve this efficiency if this method is to be widely used. ... In addition to the above methods of energy production, the use of wind power is also a promising source of energy. ...
