Consider two flat plates at standard sea level atmospheric condition.

One having $6$ ft span and $3$ ft chord, the other having $9$ ft chord which

are placed in different airstream. The freestream velocity for the

smaller plate is $100$ fps$.$ It is found that the total drag for the t wo

plates is the same. Find the airspeed for the larger plate. Assume full

laminar flow for smaller plate and full turbulent at larger plate.
