Here is how the Effectiveness when mhch is minimum value equation looks like.

0.91 = (300 \cdot \frac{0.13}{30}) \cdot (\frac{60 - 25}{60 - 10})

0.91 = (300kg/s \cdot \frac{0.13J/(kg*K)}{30}) \cdot (\frac{60K - 25K}{60K - 10K})

0.91 = (300 \cdot \frac{0.13}{30}) \cdot (\frac{60 - 25}{60 - 10})

Effectiveness when mhch is minimum value Solution

Follow our step by step solution on how to calculate Effectiveness when mhch is minimum value?

FIRST Step Consider the formula

ϵ = (mh \cdot \frac{ch}{C min}) \cdot (\frac{T H1 - T C2}{T H1 - T C1})

Next Step Substitute values of Variables

∴

ϵ = (300kg/s \cdot \frac{0.13J/(kg*K)}{30}) \cdot (\frac{60K - 25K}{60K - 10K})

Next Step Prepare to Evaluate

∴

ϵ = (300 \cdot \frac{0.13}{30}) \cdot (\frac{60 - 25}{60 - 10})

LAST Step Evaluate

∴

ϵ = 0.91
