Since plane angles are dimensionless, it follows that torque and energy have the same dimensions. 1 Watt is the power of a Joule of energy per second. It is a rotational analogy of a force. The material with 74% Mn 24% Si and 2% Al was further tested in a continuous 300 W. This was done to test the oxygen carrier capability under more conditions closer to a real circulating CLOU unit. One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore energy is required to produce work in an object. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. For other uses, see, "The unit of heat has hitherto been taken variously as the heat required to raise a pound of water at the freezing-point through 1Fahrenheit or Centigrade, or, again, the heat necessary to raise a kilogramme of water 1Centigrade.
