2. Calculate the static pressure (normalized by the freestream pressure) acting on each edge ofthe diamond airfoil.3. Calculate theCdandClcoefficients for the diamond airfoil.4. Repeat the previous drawing/calculations for the truncated diamond airfoil (i. e., the wedge)5. By what percentage does the lift-to-drag ratio improve when the rear portion of diamondairfoil is retained

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
