transmittance value of 1.5 W/m² K, what is the heat flow rate?
Question
transmittance value of 1.5 W/m² K, what is the heat flow rate?
Solution
To calculate the heat flow rate, we need to know the temperature difference and the area over which the heat is being transferred. The formula for heat flow rate (Q) is:
Q = U * A * ΔT
where: U = transmittance value (1.5 W/m² K) A = area (in m²) ΔT = temperature difference (in K)
Without the values for A and ΔT, we cannot calculate the heat flow rate.
