CONCLUSION

                                              
In the present work a Double Pipe Heat Exchanger with fin cad drawing prepared and fabricated as per drawing.
Experiments have been conducted by fixing the water flow rate at 240 liters per hour and varying the flow rate of the cold fluids in a double pipe heat exchanger with forced feed circulation of hot water & cold water treating the exchanger as counter flow and readings have been tabulated.
It is to be expected that the addition of  nano particles to the base fluid enhances the heat exchanger performance .
More experiments are to be conducted by maintaining different Inlet temperature of the hot water.
From this study I have learned more from fabrication work both inside & outside of the institution.
