One-dimensional, steady flow has velocity components u = Ax, v = 0, w = 0, where A is a constant. Place yourself in the frame of reference of a particle in this flow. You observe things as a function of time t in this Lagrangian frame of reference. Supposing that u = 1 at t = 0, derive expressions for:

. the acceleration Du/Dt that you expreience

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

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
