  Recently, CoSi has been identified to have unconventional electronic topology
due to lack of inversion center in its B20 cubic structure. The electronic
topology has been reported to be present at three nodal points found in the
band structure. Two of these nodal points are situated at the $\Gamma$ (G1 \&
G2) and one at $R$ (R1) point. Based on this, we present a study where various
transport coefficients are investigated by using \textit{first-principle} based
DFT method for the temperature (T) range 40-300 K. For the chemical potential
($\mu$) corresponding to energies of these nodal points and at the Fermi level
(E$_F$), 3D constant energy surfaces are constructed. They have shown that the
number of states available at energies of these nodal points and the E$_F$
follows an increasing trend as R1 $>$ G2 $>$ E$_F$ $>$ G1 at T = 0 K. Similar
increasing behavior seems to follow by other transport coefficients at
different $\mu$ with T rise such as electrical
conductivity($\sigma$)/relaxation time($\tau$) ratio and electronic thermal
conductivity ($\kappa_e/\tau$ = $\kappa^0$). For example, at T = 100 K, $\sigma
/ \tau$ $\sim$ 0.13$\times$10$^{20}$ $\Omega^{-1} m^{-1} s^{-1}$ at G1 whereas
its value reaches $ \sim$ 0.18$\times$10$^{20}$ $\Omega^{-1} m^{-1} s^{-1}$ at
R1 nodal point. However, Seebeck coefficient ($S$) seems to follow the trend as
G2 $>$ E$_F$ $>$ R1 $>$ G1 at any given T. The values of $S$ are obtained to be
positive at the $\mu$ corresponding to the G2, R1 and E$_F$ (except G1) which
is increasing with the rise in T. Also, the dominant charge carriers at G1
point are found to be electrons for T $<$ 225 K whereas for T $>$ 225 K, the
charge carriers are obtained to be dominated by holes. Furthermore, the doping
concentrations have also been calculated for G1, G2 and R1 points.
