Consider the case where the spanwise circulation distribution ofor a wing is parabolic:
\Gamma (y)= \Gamma _{0}(1-y^{2}/s^{2})
If the total lift generated by the wing with the parabolic circulation distribution is to be equal to the lift generated by a wing with an elliptic circulation distribution,
a) What is the relation between \Gamma _{0} values for the two distributions?
b) What is the relation between the induced downwash velocities at the plane of symmetry for the two configurations?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
