1.A stream of liquid moving as low speed leaves a nozzle pointed directly downward. The velocity may be considered uniform across the nozzle exit and the effects of friction may be ignored. At a Nozzle exit the jet velocity and area are V and A, respectinely. Determine the variation of jet are with elevation.

2.Air at 400 kPa, 270 Kelvin, enters a well-insulated, horizontal pipe having a diameter of 2cm and exits at 90kPa, 200 Kelvin. Ideal gas model for air, determine at a steady state (a) The inlet and exit velocities, in m/s and (b) the mass flow rate, in kg/s

3.A 60 -m- long steel wire must not strech more than 48mm when the tension in the wire is 6 kn. Knowing that e-200GPa, determine (a)the smallestdiameter which may selected for the wire,(b)the corresponding value of the normal stress.
