Consider the steady, two-dimensional, incompressible velocity field v=(u, v) =(ax +b)i +(-ay +cx) where a, b, and c are constants. a)-show that the given velocity field is physically possible (hint u'se one of the basic laws! ) b)-derive an expression for the pressure field pe assuming p is a smooth function of x and y.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Fluids at rest possess no flow energy. a)- true b)- false
