What is the correct formula for calculating COP of heat pump?
What is the correct formula for calculating COP of heat pump? Answer. Explanation: COPHP = (Desired Output)/(Required Input) = (Heating Effect)/(Work Input) = QH/Wnet,in = 1 + (QL/Wnet,in) Both the COP of a refrigerator and a heat pump can be greater than one. Can COPs be less than1? The coefficient of performance (COP) of refrigeration […]

What is the SI unit of respectability?
What is the SI unit of respectability? Magnetic susceptibility indicates the degree of magnetization of a material in response to an applied magnetic field. It is given as: χ=HM. Since both numerator and denominator have units A/m, susceptibility itself is a dimensionless quantity. Why magnetic susceptibility has no unit? Magnetic susceptibility( χ ) is the […]

What is an example of scientific revolution?
What is an example of scientific revolution? Perhaps the best example of such a paradigm shift in science is the Copernican revolution in cosmology: the move from a geocentric to the heliocentric view of our solar system. What I propose here is that biology is heading towards a similar scientific revolution that may shatter one […]
