In this paper we are studying about maximum R.P.M. of Permanent Magnet DC Motor. In this way we are using the regulator circuit and 1Amp. 2 Amp. 3Amp. With different voltages. R.P.M. of D.C. motor is measured by the digital type tachometer. The D.C. power supplies are obtaining by the rectifier circuit and also used the step down transformer.

Crtical heat flux (CHF) is an important characteristic of nanofluids. The CHF measurements were carried out in nanofluid research at the Center for Applied Nuclear Science and Technology. These measurements are done manually using a variable power supply and a multimeter. However, it was difficult to record the voltage and current due to the sudden break of the wire. In this study, Arduino was used to measure CHF automatically. The voltage is applied to the wire and increases automatically along with the measurement of the voltage and current in the wire. The results of the voltage and current measurements were compared with a multimeter and were not significantly different. It can be concluded that the CHF measurement system using arduino can be used to measure nanofluid CHF.
