    High Viscosity Relief valve sizing

    Thanks for your answer. The material I'm dealing with is very viscous (65,000 cP). So, when I use the iterative process to adjust for viscous flow, the value of Reynold's number quickly decreases. (R=(2800*G*Q)/(mu*sqrt(A)) So, each time I calculate an orifice size, then choose the next...

    High Viscosity Relief valve sizing

    We are to size a relief valve for a fluid with viscosity >50000 cp using API 520 but, we calculate a REynolds number too low (1). What can I do if the graph Re vs Kv starts in a Reynolds number = 34.
