Ks wy S 1 10 2 X Ki Ko XK3 ge Na The differential pressure of Sprayer oil on the previous Dade was Calculated assuming Red that the density and viscosity of light oil are 0 89 cm and 4mm2sec and those of heavy oil are 0 9g cm and 25mm2sec respectively When the actual density and viscosity differ from these values the correction of the pressure loss is reduired Correction of differential pressure by density Light oil and heavy oil have different density Therefore multiply the differential pressure of SDrayer oil on the previous page by the coefficient determined from Fig 1 for use of the sprayer for light oil and from Fig 2 for use of the sprayer for heavy oil Corrected differential pressure Standard differential pressure XK1 or K2 Correction of differential pressure by viscosity The calculation of differential pressure of sprayer oil is based on the light oil viscosity of 4mm2 sec or heavy oil viscosity of 25 mm2sec as the standard value When the actual viscosity differs from this value multiply the total differential pressure loss by the coefficient determined from Fig 3 Corrected differential pressure Standard differential Dressure XK3 Tota
