1) Any pipe line working fluid may water / steam on it one manual isolation valve suppose one side of valve 6 kg/ cm^2 pressure (i.e. up stream) and other side is “ 0” kg/ cm^2 pressure(i.e. down stream) . So how much Tourqe required for opening the valve in terms of Newton force wheather normal man can open this valve. (for reference pipe nominal bore is 100 NB )
