Answer the following statement(s) true (T) or false (F)
1. Most PLCs now have the ability to manipulate data that is stored in memory. 2. When the rung that holds the MOV instruction is false, the instruction moves data from the source address into the destination address on each processor scan. 3. In the Allen-Bradley MOV instruction, constants such as 250, 400, 5.5, etc., can be entered into the source location of the MOV instruction rather than a memory address containing the value to be moved. 4. “Data compare instructions” compare the data stored in two or more words and make decisions based on the program instructions. 5. The limit test instruction is true until it detects that the test value is within certain limits.
The indoor dry bulb temperature for AHRI rating condition "A" is:
A) 80°F. B) 67°F. C) 75°F. D) 65°F.
If you consider the ideal gas law to be an acceptable approximation for substances that have compressibility factors within 10% of 1 (i.e., between 0.90 and 1.10), determine the range of acceptable temperatures for ideal gas behavior for a gas with a pressure of 500 kPa if the gas is (a) hydrogen, (b) oxygen, and (c) carbon dioxide.
Given: P = 500 kPa, 0.9 ? Z ? 1.10 What will be an ideal response?
