A parcel of land is proposed for residential house development. The land is situated beside a river and so flooding is suspected to occur. Outline how you would go about assessing if the land is subject to flooding.

If you assess that the land does flood, outline how you would go about determining the flood levels at the property. In this case the principal objective of the assessment is to determine the flood elevation in a 100 yr ARI flood along the boundary between the creek and the parcel of land. Specify only the methodology noting that you need not present the theoretical description of the proposed method. A step by step procedure on how the assessment will be undertaken is sufficient. Specify the data required to conduct the assessment and where you would source the data.

Your submission should be in point form and should not exceed one page.

Derive an expression for the shear stress at the pipe wall when an incompressible fluid flows through a pipe under pressure. Use dimensional analysis with the following significant parameters: pipe diameter, flow velocity, viscosity and density of the fluid.

For these problems, assume air behaves as an ideal gas with R=0.287kJkgK.

1. A compressor operates at steady state and takes in air from ambient 0 kPa, gage and 200 K. The outlet pressure is 60 kPa, gage and 400 K. Determine:
   1. the mass flow rate if the inlet area is 20 cm2 and the inlet pressure is -5 kPa, gage.
   2. the minimum outlet temperature that is possible for this compressor.
   3. the isentropic efficiency of the compressor, assuming no heat loss.
   4. if there is a heat loss of 20 kJ/kg, the work required to run the compressor, and the new isentropic efficiency.
