For the heat exchanger below:

Plot the temperature distribution for the two fluids $($i$.$e$.,$ oil and water$)?$

Classify the heat exchanger based on the flow direction $($i$.$e$.,$ parallel or counter flow$)?$

Using the LMTD$,$ find the required length to achieve the stated temperature at the outlets?

If the available length at the site is less than the length that you have found in $"3",$ what would you do to ensure that the process is still achievable under this constraint?

oil:

$m_{\text{o}\text{i}\text{l}}=0\mathrm{.}15k\frac{g}{s}$

$T_{in}=100C$

$c=2131\frac{J}{k}{g}^{-}C$

$h=38\mathrm{.}8\frac{W}{m^2}-C$

$T_{\text{o}\text{u}\text{t}}=60C$

water:

$T_{in}=25C$

$T_{\text{o}\text{u}\text{t}}=50C$

$h=2250\frac{W}{m^2}-C$

$D_1=30mm$

$D_0=50mm$
