75
40 C is higher.
8 is a factor of 40
A #12 copper conductor with a insulation factor of 90 degrees C is rated at 20 amps. For 110 degrees C 35 amps, 125 degrees C 40 amps and for 200 degrees C 40 amps.
mean temperature in summer is between 35 C and 40 C
c = 25m
C or 20
40 awg <<>> The above answer is incorrect. A #40 wire is smaller that telephone wire which is #22 awg. A #8 copper conductor with an insulation factor of 60 degrees C is rated at 40 amps. For a built in safety factor, a #8 conductor with an insulation factor of 75 or 90 degrees C has a rating of 45 amps.
The difference between the GGG-40 and GGG-50 butterfly valve is the suitable temperature. The GGG-40 is recommended for 45 degrees C to 150 degrees C and the GGG-50 is recommended for 35 degrees C to 130 degrees C.
C-40 concrete has a characteristic compressive strength of 40 MPa (megapascals). To convert this to psi (pounds per square inch), you can use the conversion factor where 1 MPa is approximately equal to 145.038 psi. Therefore, C-40 concrete is equivalent to about 5,800 psi.
A #8 copper conductor with a 90 degree C insulation factor is rated at 40 amps.
35 IS a decimal. And the value of 35 c, as a decimal, depends on the value of c.
-40°F = -40°C
