$TSR = \frac{W}{m}$

Work Step by Step

Required: units for TSR Solution: Using Equation 19.9 of TSR and considering the units: $TSR = \frac{σ_{f}k}{Eα_{l}} = \frac{σ_{f} (\frac{N}{m^{2}})k (\frac{W}{m.K})}{E (\frac{N}{m^{2}})α_{l} (°C)^{-1}} = \frac{W}{m}$ Note that for the temperatures, units for K and °C are assumed to be equivalent since the two are readily convertible to one another.
