For an ideal fluid, Use dimensional analysis to express the flow Q through an orifice in terms of the density of the fluid, the diameter of the orifice D, and the pressure difference ∆p. You may recall that the expression to be found by this method tells you about how the variables in consideration are related, but it does not give you an answer, or even a full equation, to determine flow from the given variables. How you could use the expression in order to determine an equation with the coefficients require to find the magnitude of Q? Please explain.

In this question, you will carry out the algebraic equivalent to the diagrammatic analysis investigating the effect of amenities on incomes and real-estate prices. To start, let the consumer utility function be given by q1/2c1/2a1/2, where c  is consumption of “ bread ” (a catch-all commodity), q is real estate (housing), and a is amenities, which are valued by the consumer given that a’s exponent is positive. Letting y denote income, it can be shown that the consumer demand functions for...
