If turbulence decrease it lowers the heat transfer rate, here turbulence decreases which means velocity decreases which in turn reduces the reynolds number.

With increasing the baffle spacing the cross-flow velocity decrease so Re also decreases.

@Bajwa.
Turbulence will decreases then Reynolds number also decreases.
Turbulence will decreases then Reynolds number also decreases.

Baffle spacing increasing turbulence decrease means Nre decreases.

If turbulence decreases not increase.
If turbulence decreases not increase.

As the baffle spacing increases, turbulence will decreases and hence Reynolds number will increase.

The questions says about increase in baffle spacing not no.of baffle, Roht meena, I think the equivalent dia formula has baffle spacing (B) in the denominator so if B increases, D equivalent decreases as a result Re decreases. !

We know the formula of Re=(duD/m), here D=density, m=viscosity, so when we increase the baffles velocity of fluid decrease due to this Re also decrease.
