One metric for measuring requirements specification is “Correctness”. The correctness factor Cr can be calculated by Cr=R_c/(R_c+R_nv ), where R_c is the number of correct requirements and R_nv is the number of still not valid requirements. The metric Cr is used to measure percentage of requirements in the SRS that have been validated. What is the Cr of your workgroup project specification. Justify your answer.

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

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
