  We examine the dynamical behavior of accretion flow around XTE J1859+226
during the 1999 outburst by analyzing the entire outburst data ($\sim$ 166
days) from RXTE Satellite. Towards this, we study the hysteresis behavior in
the hardness intensity diagram (HID) based on the broadband ($3 - 150$ keV)
spectral modeling, spectral signature of jet ejection and the evolution of
Quasi-periodic Oscillation (QPO) frequencies using the two-component advective
flow model around a black hole. We compute the flow parameters, namely
Keplerian accretion rate (${\dot m}_d$), sub-Keplerian accretion rate (${\dot
m}_h$), shock location ($r_s$) and black hole mass ($M_{bh}$) from the spectral
modeling and study their evolution along the q-diagram. Subsequently, the
kinetic jet power is computed as $L^{\rm obs}_{\rm jet}\sim 3 - 6 \times
10^{37}$ erg~s$^{-1}$ during one of the observed radio flares which indicates
that jet power corresponds to $8-16\%$ mass outflow rate from the disc. This
estimate of mass outflow rate is in close agreement with the change in total
accretion rate ($\sim 14\%$) required for spectral modeling before and during
the flare. Finally, we provide a mass estimate of the source XTE J1859+226
based on the spectral modeling that lies in the range of $5.2 - 7.9 M_{\odot}$
with 90\% confidence.
