Generally speaking, the pressure dropping degree of pulp liquid depends upon the nominal size of piping and concentration, speed and freeness of the liquid. On the equipment designing, the calculation of pressure dropping is one of the most important things in selections of pump and nominal size of piping and control valves, however, as indicated in the Figure 1, it seems very difficult to calcualte manually in each case. Upon the requests from our customers and under the above situation, we have developed the unique calculation soft with our own invention, in order to realize an easy calculation by the personal computer. It has already been introduced for some particualr customers, but we, hereby, would like to make it open for all customers, We are very pleased, if this soft could be useful for you.
