A linear porous media (L = 2500 ft, W = 100 ft, H = 50 ft, k = 75 md, q = 17%) is flowing dry gas (sp. gr. = 0.78 and viscosity = 0.0173 cp) at 120 C. The upstream is 1800 psi and flow rate is 1.2 MM SCF/day. Find: 

1. Gas flow rate - 

2. Actual and apparent velocity Ha 

3. Average reservoir pressure.
