1. Illegal fund-raising refers to the behavior that an entity or indivial raises funds from the public by issuing stocks, bonds, lotteries, investment fund securities or other creditor's rights certificates without the approval of relevant departments in accordance with legal proceres, and promises to repay the principal and interest or give returns to the investors in currency, material object or other ways within a certain period of time
the crime of financial fraud refers to the act of defrauding public or private property or the credit of financial institutions and damaging the order of financial management by making up facts or concealing the truth for the purpose of illegal possession.

2. The bigger the diameter of the pipe, the smaller the diameter of the pipe. It won't affect the flow rate. It's just that the flow rate in the small pipe is faster
the steps to select the pipe according to your question
calculate the volume flow: (10 / 60) / (0.7 / 0.1) = 0.0238m3/s, and the nominal flow of the compressor is the flow of the standard state. When calculating the flow in the pipeline, it should be converted into the flow at the outlet of the compressor
determine the flow rate according to the pipe material. Here I give a more common 15m / s
pipeline cross-sectional area 0.0238/15 = 0.0015873m
pipeline diameter: R ^ 2 = 0.0015873 / pi = 5.053 * 10 ^ - 4m
R = 0.0225m
DN = 2 * 0.0225 = 0.045m = 45mm
it's usually DN50. Or G2
if important pipelines need to be checked. The stress of laminar flow on the pipe wall caused by friction should be considered in the check.

only gravity does work after leaving the platform
