Intermediate Macro

Please help me find an example

The Quantity Theory of Money in its Classical form assumes the velocity of money is a constant. Since V is defined as Nominal GDP/money supply, and since data on these two macro variables is readily available, it is possible to calculate velocity from them. Can you help me to look up the data and produce a time series for velocity over a period of 20+ years to see if it is constant? Addition, look at the variables in the quantity equation and their recent behavior in the wake of extreme fiscal expansion and monetary looseness in the US. Can you use these data to explain why inflation has been relatively low, but expectations of inflation seem to be rising
