4–48 In a meat processing plant, 2-cm-thick steaks (k 5 0.45 W/m·K and a 5 0.91 3 1027 m2 /s) that are initially at 25°C are to be cooled by passing them through a refrigeration room at 211°C. The heat transfer coefficient on both sides of the steaks is 9 W/m2 ·K. If both surfaces of the steaks are to be cooled to 2°C, determine how long the steaks should be kept in the refrigeration room. Solve this problem using analytical one-term approximation method (not the Heisler charts).

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
