Single phase pressure drops in micro tubes were investigated through an experimental measurement and a numerical simulation. Experimental Po was obtained in circular micro tubes with 87 and 118 ㎛ diameter with distilled water. Experiments were carried out in laminar flow region with varying the Re 15-450 for the 87 ㎛ diameter tubes and 60-1300 for the 118 ㎛ diameter tube. No early transition from laminar to turbulent flow was detected for the experimental range. The computational estimation of pressure drop in the 87 ㎛ diameter tube was performed with the aid of CFD software. Boundary conditions from experiments were used for the numerical simulation. The results of experimental and numerical studies showed a good agreement with the conventional macro theory.
