How high above the ground is a baseball with a mass of 0.17 kg that has a potential energy of 67 J?

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

what is the question here. i think you messed up.
