Heat Transfer from Stream of Gas flowing in Turbulent Motion Solution

Follow our step by step solution on how to calculate Heat Transfer from Stream of Gas flowing in Turbulent Motion?

FIRST Step Consider the formula

h ht = \frac{16.6 \cdot c p \cdot {(G)}^{0.8}}{D^{0.2}}

Next Step Substitute values of Variables

∴

h ht = \frac{16.6 \cdot 0.0002kcal(IT)/kg*°C \cdot {(0.1kg/s/m²)}^{0.8}}{{0.24m}^{0.2}}

Next Step Convert Units

∴

h ht = \frac{16.6 \cdot 0.8374J/(kg*K) \cdot {(0.1kg/s/m²)}^{0.8}}{{0.24m}^{0.2}}

Next Step Prepare to Evaluate

∴

h ht = \frac{16.6 \cdot 0.8374 \cdot {(0.1)}^{0.8}}{{0.24}^{0.2}}

Next Step Evaluate

∴

h ht = 2.93074512232742W/m²*K

LAST Step Rounding Answer

∴

h ht = 2.9307W/m²*K

How to Evaluate Heat Transfer from Stream of Gas flowing in Turbulent Motion?

Heat Transfer from Stream of Gas flowing in Turbulent Motion evaluator uses Heat Transfer Coefficient = (16.6*Specific Heat Capacity*(Mass Velocity)^0.8)/(Internal Diameter of Pipe^0.2) to evaluate the Heat Transfer Coefficient, The Heat Transfer from Stream of Gas flowing in Turbulent Motion where fluid does not flow in smooth layers but is agitated. Heat transfer occurs at the channel wall. Turbulent flow, due to the agitation factor, develops no insulating blanket and heat is transferred very rapidly. Heat Transfer Coefficient is denoted by h_ht symbol.

How to evaluate Heat Transfer from Stream of Gas flowing in Turbulent Motion using this online evaluator? To use this online evaluator for Heat Transfer from Stream of Gas flowing in Turbulent Motion, enter Specific Heat Capacity (c_p), Mass Velocity (G) & Internal Diameter of Pipe (D) and hit the calculate button.
