Gaseous nitrogen is in isothermal turbulent flow at 25C through a straight length of horizontal pipe with 3-in. inside diameter at a rate of 0.28lbm/s. The absolute pressures at the inlet and outlet are 2atm and 1atm, respectively. Evaluate viscous loss hf assuming ideal gas behavior and radially uniform velocity distribution.
