7. Temperature, Deposition (mpd) and Flow Conversion factors and formulas
Temperature
°F = (1.8 x °C) + 32°C = (°F - 32) ÷ 1.8°K = (°F + 459.67) ÷ 1.8
Deposition (Scale in Coupons) "mpd"
mpd = M x 1000 ÷ (A x T)M: Weight increment (gr.)
Bottle / Jar test dosage ratio
Fluids properties
mpd: Milligrams per day / in2
A: Coupon Surface Area (in2)
µl = microliters of product
µl = {V x 100 x ppm) ÷ (1E06 x % C) }V: Volume of sample to be treatedppm: Dosage ratio to evaluate products >>>> Benchmark: Field dosage in C: % dilution of evaluated productsGeneric bottle test uses 100ml of sample >>>> µl = (10 x ppm) / C
°API = (141.5 ÷ S.G) - 131.5S.G : Specific gravity of the oil @ 60°FS.G. = 141.5 ÷ (°API + 131.5)
