$60,000$ lb$/$hour of Aniline will be heated from $75\backslash$deg C to $125\backslash$deg C in a Shell and Tube using $56\backslash$deg API gasoline so that the temperature drops from $250\backslash$deg C to $175\backslash$deg C$.$ If $1$ in OD$,16$ BWG $16$ ft long tubes are used arranged in a triangle with a pitch of $1\mathrm{.}25$ in$.$ As well as setting a combined minimum dirt factor of $0\mathrm{.}004$ h$.$ft$^2\backslash$deg F$/$Btu and a maximum pressure drop for both streams of $10$ psi. Determine the size of the shell then calculate the evaluation whether the size is suitable or not? Then draw it$.$
