For the venture section, calculate the velocity,mass flow rate, volume flow rate and the pressure at station two (the throat)with the properties of station one are as follows: Pressure is equal to 1.05 Bar, the temperature is recorded at 72 degrees Fahrenheit, and the inlet velocity is recorded at 50mph. The inlet is 5.0ft^2 while station two is 1.0 ft^2.
