36a2 - 60a + 25 = 36a2 - 30a - 30a + 25 = 6a(6a - 5) - 5(6a - 5) = (6a - 5)(6a - 5) = (6a - 5)2
10a-37=6a+51 -6a -6a subtract 6a from both sides and the 6a's cancel 4a-37=51 +37 +37 4a=88 /4 /4 a=22
6a
-6a + 8 = 2 -6a = -6 a = 1
6a times 4 is equal to 24a by: 6a x 4 = 24a 24a = 24a
Hi, Both are API Standards,which define the specification about wellhead is 6A. and which is define the specification about centrifugal pump is 610. Refer API STANDARD. All the best.
Both deal with valves. API6FA is for API 6A and 6D. API607 applies to soft-seated, quarter-turn valves.
It's quite easy. API 6A speaks about wellhead and x-mas tree equipment, API 6D speaks about pipeline valves. If you are phisically looking to one valve, you can also understand if it belows to 6A or 6D giving a look to the valve label. On the label you can read the class of the valve. If the class is 2000 or 3000 or 5000 or 10000 or 15000 or 20000 the valve is 6A. If the class is 125 or 150 or 300 or 400 or 600 or 900 or 1500 or 2500 the valve probably is a 6D ("probably" because the same classes of API 6D are used also by other API standards, like 594, 600, 608, ecc ecc).
BS Standard is a Specification for steel globe and globe stop and check valves (flanged and butt-welding ends) for the petroleum, petrochemical and allied industries the list below are standards that i wish help to you API 600 API 6D API 6A ASME B16.5 ASME B16.34
As per API 6A temperature classification, -20 deg F to 250 deg F operating temperature range.
Divide by 6a: 6a(a + 3b)
36a2 - 60a + 25 = 36a2 - 30a - 30a + 25 = 6a(6a - 5) - 5(6a - 5) = (6a - 5)(6a - 5) = (6a - 5)2
10a-37=6a+51 -6a -6a subtract 6a from both sides and the 6a's cancel 4a-37=51 +37 +37 4a=88 /4 /4 a=22

-6a + 8 = 2 -6a = -6 a = 1
12a2b + 6a = 6a(2ab + 1)
