Thank you. You are correct but in general the sizes will be increased only if there is already existing pump installed and or if u r extending the network to some other additional buildings etc. in order to satisfy the existing pressure head requirements. In normal case, as per the standard we don’t increase than required..
you use fixed flow rate for 2nd landing valve because the inlet pressure is higher, so fire fighters shall adjust the k factor of the nozzle. if you use same k factor, you may endup with higher flow rate at the pump.
good sharing!
Thank u
great video
Thanks
good work , but you can increase the size of pipe riser to decrease the total required pressure or you will use PRV

You are correct.
Maximum 1000 gpm for sprinklered building and 1250 gpm for non sprinklered building
Yes. Absolutely agree
