The country has substantial hydro-electric power resources. During the British period Mr. J. M. Myres had made a guess estimate of a minimum potential of 3.5 million Kw. and a maximum of 8 million Kw. But this was rather an incomplete and under-estimate. The economically exploitable hydro-power potential of the country has been assessed by the Central Water and Power [...]
The various thermoelectric effects in relation to thermodynamic conversion of heat to work are as follows: 1. Seebeck Effect 2. Peltier Effect 3. Thomson Effect 4.Joule Effect. 1. Seebeck Effect: If two dissimilar materials are joined to form a loop and two junctions maintained at different temperatures, an e.m.f. will be set up around the loop. The magnitude of current [...]
In this article we will discuss about the design of wind turbine rotor with the help of suitable diagrams. In a propeller type wind turbine, the following two forces operate on the blades: 1. Axial Thrust: It acts in the same direction as that of the flowing wind stream. 2. Circumferential Force: It acts in the direction of wheel rotation [...]
