An air stream dot{M}_L = 5.5  kg/s, cp_L=1 kJ/(kgK) is to be heated in a plate heat exchanger from θ_L′=20∘C ′ to θ_L′′=150∘C. For this purpose, a flue gas stream dot{M}_R = 7.22, cp_R=1.1 kJ/(kgK) with a temperature of θ_R′=300∘C is available. The overall heat transfer coefficient is k=15 W/(m^2*K).
What is the required heating surface AAA if the fluid streams are arranged in counterflow?

During last year acceleration a top speed of 100 km/h was reached. Due to big improvements in the new drivetrain, the new vehicle reaches a top speed of 120 km/h. The aerodynamics chief has some worries about the stability of the rear wing bracing due to the higher aerodynamics load. Given the geometry below, by how much % does the bearing force in point A change in comparison to last year? (The aerodynamic package did not change and therefore some values can be assumed for both vehicles). Give answer rounded to one decimal place.

CL=3.8     CD=1.2     A=1 m²     rho=1.1 kg/m³     L1=50 mm     L2= 100 mm     H1= 125 mm     H2= 165mm
