A pipe in an industrial plant is designed to carry a fluid of density 1500 kg m–3 at a speed of 3 m s–1. Any faster than this and the flow could become turbulent, with undesirable results. Any slower than this and the fluid could start to congeal on the sides of the pipe. The fluid is to be carried from a holding tank which is at a pressure of Pt to a manufacturing line at atmospheric pressure (Patm= 100kPa) which is 2.5 m below the holding tank. At what
pressure must the tank be maintained?

Show how the Romer model exhibits a scale effect in levels, that is, a larger economy will
be a richer economy. Give the demand and supply effects. Explain the two opposing effects
of SR on per capita output.
Prove that in the Romer model, the long run growth rate of the economy is determined by
the parameters of the production function for ideas and the rate of growth for researchers
which is ultimately given by the population growth rate. (Romer Model)
The Production of new goods, or new ideas, requires the possibility of earning profits and
therefore necessitates a move away from perfect competition. Explain this in the context of
Romer model
Explain the two characteristics of Public goods; a) Non-rivalrous and b) low degree of

associated with the nature of Data on Ideas. (Romer Model)
