WebThe stream table lists important variables for all process streams in an organized, tabular format. The rows and columns are customized for the application. Typically, rows would be variables like composition, flow rate, temperature, and pressure; and columns would normally correspond to points before and after pieces of equipment. WebConservation of energy tells you that the pressure in the reduced area will be lower because the velocity is increased (speeding a fluid up lowers it pressure, some what counter intuitive because we think of pressure in terms of force not potential energy) Flow rate (Q) = velocity * Area. Q1 = Q2 v1 * A1 = v2 * A2.
