Air flows from a 10cm pipe in which the temperature and pressure are 4-C and 280kpa, respectively, into a 5cm pipe in which the pressure is 147kpa gage. Calculate the velocity and discharge in each pipe, assuming isothermal conditions, standard atmospheric pressure and no losses. The gas constant for air is 280N-m/kg-K.
Natural gas, which is essentially methane is being pumped through a 1m ID steel pipe for a distance of 100 km at a rate of 2 kmol/s. It can be assumed that the flow is isothermal at 289 K. The pressure at the end of the line is 170 kPa. Assuming that the viscosity of the gas is 1.08963x10-5 Pa-s, calculate the pressure (kPa) at the pump discharge.
