Question

The upper specification limit for this product =4.120 ∘mm (round your response to three decimal places). The lower specification limit for this product = mm (round your response to three decimal places) The process is known to operate at a mean thickness of 4.0 mm. The process capabiliy index (C pk )=2.000 (round your response fo throe decimat pticest) The upper speciication limit lies about standard devations trom the centerine (mean thickness). The specifications for a plastic liner for a concrete highway project calls for thickness of 30 mm±0:10 mm. The standard deviation of the process is estimated to be 0.02 mm. The upper specification limit for this product = mm (round your response to three decimal places)

Answer 1

The engineer can calculate the time recorded using the equation v = f * λ. By rearranging the formula s = vt, the engineer can solve for t to determine the time recorded when the coating is the correct thickness.

Step-by-step explanation:

The engineer can use the equation v = f * λ to calculate the time recorded.

Given that the frequency (f) of the sound waves is 25 kHz and the wavelength (λ) is 0.076 m, we can substitute these values into the equation to find the velocity (v) of the sound wave in the coating.

Then, using the formula s = vt, where s is the thickness of the coating (1.00 mm) and t is the time recorded, we can rearrange the formula to solve for t.

Substituting the known values, we can calculate the time recorded when the coating is the correct thickness.
