  The flow near a moving contact line depends on the dynamic contact angle,
viscosity ratio, and capillary number. We report experiments involving
immersing a plate into a liquid bath, concurrently measuring the interface
shape, interfacial velocity, and fluid flow using digital image processing and
particle image velocimetry. All experiments were performed at low plate speeds
to maintain small Reynolds and capillary numbers for comparison with viscous
theories. The dynamic contact angle, measured in the viscous phase, was kept
below $90^{\circ}$, an unexplored region of parameter space. An important aim
of the present study is to provide valuable experimental data using which new
contact line models can be developed and validated. Interface shapes reveal
that the strong viscous bending predicted by theoretical models is absent in
the experimental data. The flow field is directly compared against the
prediction from the viscous theory of \cite{huh1971hydrodynamic} but with a
slight modification involving the curved interface. Remarkable agreement is
found between experiments and theory across a wide parameter range. The
prediction for interfacial speed from \cite{huh1971hydrodynamic} is also in
excellent agreement with experiments except in the vicinity of the contact
line. Material points along the interface were found to rapidly slow down near
the contact line, thus alleviating the singularity at the moving contact line.
To the best of our knowledge, such a detailed test of theoretical models has
not been performed before and we hope the present study will spur new modeling
efforts in the field.
