Pumping apparatus driver/operators must be familiar with the different types of nozzles carried on their apparatus. how would a particular type of nozzle being used affect the hydraulic calculations that must be performed by the driver/operator?

Each type of nozzle has its discharge pressure and optimum flow rate which affect the hydraulic calculations.

Explanation:

There are different types of nozzles used for pumping operation. Each type of nozzle has its discharge pressure and optimum flow rate. And in hydraulic calculations, various nozzle parameters (such as discharge pressure and optimum flow rate) are needed. Therefore, the capabilities of these nozzles to generate the proper fluid volume and pressure must be carefully understood.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

no simpler subs form complex ones. synthesise = make
