One could argue that the problem faced by Henry Woodward and Mathew Evans was a direct result of an incomplete step/modify the prototype based on test results in the engineering design process.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

Estimate the change in specific internal energy au and specific enthalpy h from inlet to outlet for ethylene glycol (a liquid) flowing through each of the following devices: (a) a heat exchanger where the glycol temperature increases from 20 °c to 80 °c; (b) a pump operating at about 25 °c and increasing the glycol pressure from 100 kpa to 8 mpa.
