low-pressure

A massive winter storm is coming together as two low pressure systems are merging over the U.S. East Coast.

Then, when the system is depressurized there are other systems that inject water at low pressure.

Its first cost and expense in working to be much less than that of the Watt low-pressure steam vacuum engine.

The down-stroke began with a comparatively low pressure of steam under the pole.

The conversion of the other, a 63-inch low-pressure vacuum engine at Wheal Gons, will be traced in this chapter.

The Boulton and Watt low-pressure engine did not work well with the high steam, and the water rose in the mine workings.

The one with low-pressure steam and vacuum, the other with high-pressure steam and without vacuum.
