The invention relates to a system for determining material surface erosion caused by impingement of nanofluids on pipes carrying nanofluids, comprisinga nozzle device having atleast four nozzles disposed equidistantly on a test- specimen surface; a device for holding the test specimen having atleast four sample holders, and a metal rod; a first stand having a plurality of clamping means, the nozzle assembly and the sample holders mounted on the first stand being movable by means of said plurality of clamping means; and a dial attached to said metal rod to measure the angular tilt of the nozzle; a second stand holding a tank attached to a sump, the tank accommodating the assembly of the nozzle device, specimen holders with test specimens, and the first stand, the tank having an opening flowably connected via a triangular channel to the sump for collecting the nano-fluid after being impinged by the nozzle device on the surface of the test specimen; a nanofluid distribution device having at a first end a plurality of second tee- joints, the second end being closed; and a plurality of pumps controlling delivery of the nanofluid from the nozzles being measured through corresponding number of flow-meters and a series of first plurality of tee-joints, an electronic circuitory monitoring a plurality of solenoid valves to prevent over-heating of the pumps to control flow from the pumps to the nozzles.
