A radon mitigation system in a house uses a fan to draw air from under the foundation through a pipe and exhausts it to the atmosphere. The pipe has a manometer attached. The specific gravity of the liquid in the manometer is 0.832. The height of the liquid in the leg of the manometer inserted in the pipe is 2.1 cm above the liquid level in the leg that is open to the atmosphere. What is the gage pressure in the pipe?
