ESDU 74029 gives methods of applying the friction factor data of ESDU 66027 to the case of isothermal or adiabatic flow of a gas. The procedure to be followed is indicated in each case by a calculation flow chart, and data are provided in graphical form for gas specific heat capacity ratios from 1 to 1.67 to assist in the calculations. A compiled Fortran program of the method is provided (ESDUpac A7429) and within ESDUview, a user-friendly interface that runs under MS DOS and prompts on-screen for input data.
