Constant relative humidity lines are uphill curved lines to the right

Constant wet bulb temperature lines are downhill straight lines to the right.

Constant specific volume lines are downhill straight lines to the right.

Constant enthalpy and WBT lines are not coincident. The enthalpy lines are uniformly spaced, while the WBT lines non uniformly spaced
