THIS USER ASKED 👇
At the metal-casting company where you work, you must set up a conveyor system to move castings from the furnace to the heat treatment area 55 yards away. the castings cool at the rate of 0.3°f (degrees fahrenheit) per second and must not be allowed to cool more than 7°f before being heat treated. what is the minimum speed, in feet per second, that the conveyor must move?
THIS IS THE BEST ANSWER 👇
2.35 yards / second or 7.07 tr / sec
Step by step explanation:
The length to be covered is 55 yards.
The casting cools at a rate and the temperature cannot be allowed to cool more than .
We know that,
By the time the temperature reaches , it will take around,
, so it will take about 23.33 seconds.
Also, 55 yards =
So the minimum speed at which the carrier must move,
Hence, the speed of transport is 7.07 feet per second.
