2.34 A supersonic aircraft travels at 2800 km/hr at an altitude of 27 km. Determine the Mach number for the airplane. The wing width (chord) is 7 m. Assume the wing can be treated as a flat plate and determine the Reynolds number at the trailing edge and the position at which transition from a laminar to turbulent boundary layer occurs.

A tremendous force is generated when waterfreezes into ice and expands in volume by 9.0%. Suppose a 1.000-m3cube of liquid water freezes into ice that is 1.000 m on a side by1.090 m tall. How many 68-kg students would the ice be able tolift? Determine this by calculating the amount of force on the top1.000-m2face that would be required to squeeze 1.090 m3of iceback to 1.000 m3, assuming all of the volume change occurs alongthe vertical direction

When a person ice skates, the surface of the ice actuallymelts beneath the blades, so that he or she skates on a thinsheet of water between the blade and the ice.( a ) Find an expression for total friction force on the bottomof the blade as a function of skater velocity V , bladelength L , water thickness (between the blade and theice) h , water viscosity μ , and blade width W .( b ) Suppose an ice skater of total mass m is skatingalong at a constant speed of V 0 when she suddenlystands stiff with her skates pointed directly forward,allowing herself to coast to a stop. Neglecting frictiondue to air resistance, how far will she travelbefore she comes to a stop? (Remember, she iscoasting on two skate blades.) Give your answer forthe total distance traveled, x , as a function of V 0 , m ,L , h , μ , and W .( c ) Find x for the case where V 0 = 4.0 m/s, m = 100 kg,L = 30 cm, W = 5.0 mm, and h = 0.10 mm. Do youthink our assumption of negligible air resistance is agood one?
1) When an incompressible fluid flows through a restricted (narrower) portion of a pipe, mass flow is preserved, so it: sloshes back and forth. must speed up. remains at constant speed slows down. creates a shock wave. 2) When an incompressible fluid moves from a wider pipe into a narrower one, it speeds up. This means that the wider portion must do work on the fluid (to accelerate it), and therefor the pressure there... goes to zero. is lower than in the narrow portion. is higher than in the narrow portion. is the same as in the narrow portion. cannot be calculated. 3) Normally, when the temperature of a solid, liquid, or gas increases, it expands, i.e., its volume V increases (and its mass density: ρ = m /V decreases). Because of its relatively strong hydrogen bonds, water ice forms an orderly, hexagonal lattice structure that requires the molecules to be about 9% further apart than when in the liquid phase, which…
