Studies on the Computer Aided Design of Power Sprayer (I)

Basic Caleulation of Pump

Abstract

This study is applying the digital computer to the power sprayer design.
The algorism of power sprayer design must be standardized in the first step. The next step is to prepare a flow chart which outlines generally the design, and the problems are solved automatically by the digital computer.
In this report, the volumetric efficiency and pumping efficiency were calculated in addition to the design, using the coefficients of loss and the torque loss in the theoretical equations which were obtained from the experimental data and structural size of power sprayer.
The flow charts of basic calculation of power sprayer design are shown in Fig. 3-6. This design was programed by FORTRAN, and calculated by the digital computer TOSBAC-3400/41.
The main sizes and performance of power sprayer used as the model in this report were shown in Table 3 to be compared with the results designed by the computer.
The sufficiency of programing was recognized.
