1. ImR Chart Exercise 1 - revised

I need these 3 parts answered for a review activity.

What’s the the answer please

In a continuous review inventory system, the lead time for doorknobs is 5 weeks. The standard deviation of demand during thelead time is 85 units. The desired cycle-service level is 99 per-cent. The supplier of door knobs streamlined its operations andnow quotes a one-week lead time. How much can safety stockbe reduced without reducing the 99 percent cycle-service level?

Select atleast two testing devices from among the categories (you may go beyond two). Discuss its application and methods of use. a. testing for speed (Tachometer), b. Testing of Air Consumption (Air-box method/viscous-flow meter), c. testing of exhaust smoke (Bosch/Hartridge/PHS), d. testing of exhaust emission (flame ionization detector/spectroscopic analyzers/gas chromatography) e. testing of torque (absorption dynamometer/transmission dynamometer).

I need help solving these 3 simple parts, if you can not answer all 3 parts then please leave it for another tutor, thank you.

You’re testing a system that involves a fan, water pump, and compressor. The components are turned ON in sequence and sensor readings are taken, as per a written protocol that you’re following. The system is running as expected after the fan and water pump are turned ON. However, when you turn ON the compressor, it runs for about thirty seconds then stops, consistently. Swapping out the compressor for a different one seems to solve the problem. What could have been the issue with the bad compressor?

8. Why do experiments have a control group as part of the design? to see if the treatment (changing the independent variable) has any effect to use as a backup, In case the experiment fails the first time O to help the scientists determine which varlable is the dependent variable to minimize the number of varlables in the experiment

A. A student establishes the time constant of a temperature sensor by first holding it immersed in hot water and then suddenly removing it and holding it immersed in cold water. Several other students perform the same test with similar sensors. Overall, their results are inconsistent, with estimated time constants differing by as much as a factor of 1.2. Offer suggestions about why this might happen. Hint: Try this yourself and think about control of test conditions. B. Which would you expect to be better suited to measure a time-dependent temperature, a thermal sensor (e.g., a thermocouple) having a small diameter spherical bead or one having a large diameter spherical bead? Why?

Pls Comment on the use of layout and other elements in the washing machine control panel. If errors occur based on this layout, walk through the accident scenario. Suggest potential ways of improving the interface to avoid a similar problem occurring.
