Helium at 20C and low pressure flows past a thin flat plate 1 m long and 2

Question:

Helium at 20°C and low pressure flows past a thin flat plate 1 m long and 2 m wide. It is desired that the total friction drag of the plate be 0.5 N. What is the appropriate absolute pressure of the helium if U = 35 m/s?
