The developed algorithm of calculation of the compressor unit network characteristic has a number of disadvantages: impossibility of calculation of the pneumatic network with ring pipelines; absence of protection against wrong choice of the most loaded direction of air supply and the most remote consumer in it at drawing up the calculation scheme of the pneumatic network; necessity of input of the pipeline diameter by an arbitrary number at the length equal to zero, arising at the equivalent transformation of the pneumatic network; repetition of a number of operators, making the pneumatic network equivalent to zero.
