Formula for calculating accumulator volume

I’m seeking help from experts, based on API 614. During the switching process of the unit’s main and auxiliary oil pumps (when the main pump stops and the auxiliary oil pump starts), the accumulator must ensure that the control oil pressure rises to 0.35 MPa within 4 seconds. How should the volume of the accumulator be calculated in this case? :L

Your question lacks complete parameters; by how much does it increase? What is the relationship between this increasing value and the normal operating value? Is it too big or too small?

Use the calculation formulas from the accumulator calculation section of the hydraulic transmission design manual. . . . .
