A $1-2$ shell and tube heat exchanger will be used to heat $4$ kg$/$s of a liquid food $($density $1020$ kg$/$m$^3,$ Cp $=3850$ J$/$kg K$,$ M$=0,5$x$10^-3$ k$=0,68$ w$/$m$.$k$)$ from $5\backslash$deg C to $75\backslash$deg C by $10$ kg$/$s of liquid water at an inlet temperature of $95\backslash$deg C$.$ Heating medium flows through the shell$-$side. The fouling coefficient for the shell side is estimated as $0,004$ m$^2.$kw$.$ The heat transfer coefficient for the shell side will be assumed as $10000$ w$/$m$^2.$K$.$ The pipe has inner and outer diameter of $22,1$ mm and $25,4$ mm respectively. S$=$ SL $=5$CM$.$ Number of tubes is $86$

$$f the proposed length of the sthe is $10$ m $,$ is this sthe satisfactory for your requirement
