i can not edit fluid speed by lua

[860000023]

i need to modify crude-oil fluid speed to fast.
Before 0.17 ,i edit 　pressure_to_speed_ratio = 0.4,

　　flow_to_energy_ratio = 0.59,

but 0.17 can not find this. Can someone tell me where I need to modify now? Thank you very much

Probably the best programming example that might meet some of your needs is https://mods.factorio.com/mod/high-pressure-pipes. What that mod does create a new tier of pipes with increased throughput of fluids. Based on the code, it looks like the variable xxx.fluid_box.height can be modified to change the throughput capacity of a pipe for fluids. In this case "xxx" is an entity, which deals with fluids. In your case, you might need to add some conditional statements, to ascertain if it is crude oil or not, or create a new tier of fluid logistical entities which can only transport crude oil.

Another option, would be to create a new fluid, say super-heated crude oil, the recipe would be 2 crude for 1 super-heated crude oil, likewise the reverse recipe would be 1 super-heated crude oil into 2 crude. Net result, you would be able to convert crude oil into super-heated oil, and move through crude oil through the pipes twice as fast, then revert it back to crude.

A third option, is to change the recipes of basic oil processing, advanced oil processing, and anything else that uses crude oil as an ingredient. The example with basic processing the replaced recipe could be 100 crude oil producing 90 petroleum.
