The pressure drop across a perforated plate depends on factors like plate thickness, hole diameter, and fluid properties. In general, pressure drop can be estimated empirically or calculated using the Darcy-Weisbach equation or the K-factor method. Accurate values would require specific plate and fluid details for a precise calculation.
