Function being fit:įirst derivative of the function with respect to parameter A The genfit function requires the first derivatives of the function with respect to the parameters being fitted. As a transportation fuel it is clean but batteries to store it on-board have limited capacity and are heavy.ġ.24 Use the Matcad genfit function to fit the data to Antoine's equation. It is easy to transport but expensive to store. Electricity has the most uses though it is expensive. However, fuel cells are currently being developed which will allow for the conversion of gasoline to electricity by chemical means, a more efficient process. It can be used to generate electricity by burning it but the efficiency is limited. It is more convenient to transport and store than coal. Gasoline is an important transportation fuel. Otherwise it is messy to handle and bulky for tranport and storage. The obvious advantage of coal is that it is cheap if it is used as a heat source. 1.11.ī) The electrical energy can directly be converted to other forms of energy whereas the coal and gasoline would typically need to be converted to heat and then into some other form of energy before being useful. Taking the exponential of both sides and rearranging: Psea 1atmġ.13 The same proportionality applies as in Pb. ´ Denver 1 Separating variables and integrating: µ dP = µ P ¶P sea First calculate K based on the earth measurement then gMars based on spring measurement on Mars. The force on a spring is described by: F = Ks x where Ks is the spring constant. Solve this equation by setting t(F) = t(C). Chapter 1 - Section A - Mathcad Solutions 1.4 The equation that relates deg F to deg C is: t(F) = 1.8 t(C) + 32.
