Single-Phase Gas Flow Subsonic Calculator

qsc=1248CdAPuk(k−1)γgTu[(PdPu)2/k−(PdPu)(k+1)/k]q_{sc}=1248C_dAP_u\sqrt{\frac{k}{(k-1)\gamma_gT_u}\left[\left(\frac{P_d}{P_u}\right)^{2/k}-\left(\frac{P_d}{P_u}\right)^{(k+1)/k}\right]}

Enter the required inputs, confirm the units, and run the calculator to solve q_sc. Review the formula source and assumptions before using the result in engineering work.
