The heat transfer enhancement in shell and tube heat exchanger can be done by adding Nano particles to the base fluid. The heat transfer rate between hot and cold fluid shows increasing sign with low to high mass flow rate.. Mass flow rate can be controlled and monitored with the help of valve fixed to the shell inlet. Comparing volume concentration of Titanium Nitride from low to high heat enhancement lies linearity. As volume concentration rises in base fluid affect the viscosity of exchange fluid in turn friction of contact fluid increases. Increased mass flow rate and heat transfer helps to find efficiency. The result shows for the controlled same flow rate with common inlet temperature transfer rate of nano fluid is slightly higher with water. Efficiency increase for about 7.47% for water to nanofluid. The effectiveness increase for about 36.6% for water to nanofluid. The LMTD increased for about of 33.6°C and heat transfer rate increases for about 0.4879 kW for three concentrations at one flow rate. Rising the mass flow rate of nano fluid inference in increasing heat transfer.
