the contour of the bucket. When the water-jet contacts the bucket‚ the water exerts pressure on the bucket and the water is decelerated as it does a "u-turn" and flows out the other side of the bucket at low velocity. In the process‚ the water ’s momentum is transferred to the turbine. This "impulse" does work on the turbine. For maximum power and efficiency‚ the turbine system is designed such that the water-jet velocity is twice the velocity of the bucket. A very small percentage of the water ’s

AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

can flow from high to low pressure due to the weak Coriolis force. If the air is not made to rotate near the equator region‚ storm cannot result. Hence‚ Hurricanes also do not form. Coriolis force is considered as a force resulted from conservation of angular momentum. It solves the problem of spinning and every point on the globe changes the direction as well as acceleration. The speed of rotation of objects is about 25000 miles per day on the equator while the objects remain stationary near the poles

could easily be considered the one person who started the land conservation explosion with his writings and theories. Holmes Rolston III also argued that species protection was a moral duty (Rolston 1975). In the mid 1970 environmental ethics was gaining momentum and society was starting to take a look at what we as humans were doing to nature because of our choices. Society’s moral views towards nature were starting to shift to conservation rather than the get what we can get attitude. Current Events

network of pipes and fittings of different sizes from an overhead tank. The estimation of losses in these networks can be done with the help of this equation which is essentially principle of conservation of mechanical energy. Formal Statement: Bernoulli’s Principle is essentially a work energy conservation principle which states that for an ideal fluid or for situations where effects of viscosity are neglected‚ with no work being performed on the fluid‚ total energy remains constant. Bernoulli’s
