Consider a double wedge airfoil with a maximum thickness at 0.5c operating at mach numbers of 2, 4 and 6.
a. calculate the values of lift (cl) and drag coefficients for the 5% and 10% thick airfoils at angle of attack = 1 degrees. use these values to calculate the lift curve slope (dcl/dalpha) and lift-to-drag ratio (l/d).
b. discuss the effects of mach number and maximum thickness on lift curve slope l/d.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
