Model MSH & MH Sizing Information

Step 1: Solve for the unknown using the formulas stated below

Variables To Solve For:

KW Requirement:		GPH x			°F ∆T x 0.00244 =				KW
Temperature Rise:			KW x 410 ÷			GPH =		°F ∆T
Flow Rate:	KW x 410 ÷			°F ∆T=			GPH

Metric Conversions

Liters x 0.2641 = Gallons Gallons x 3.79 = Liters Gallons x 0.003785 = m3 m3 x 264.2 = Gallons 1OC ∆T  =  1.8°F ∆T OF  =  (OC  x  1.8)  +  32

OC  =  (OF  -  32)  x  0.556

Watts/Sq.Cm. x 6.4 = Watts/Sq.In.

Watts/Sq.In. x 0.155 = Watts/Sq.Cm.

psi x 0.06896 = Bar Bar x 14.5 = psi

psi x 6.86 = kPa kPa x 0.1456 = psi Kg/cm2 x 14.28 = psi psi x 0.07 = Kg/cm2 Lbs x 0.4536 = Kg Kg x 2.2 = Lbs
