It displays the static pressure loss over a length of 100 feet for a specific duct size and airflow.
<h2>What is a ductulator?</h2>
People who work in the HVAC and construction industries use ductulators to size the ductwork in mechanical systems. It enables you to select the volumetric flow rate after selecting the static pressure you wish to keep in the duct. The ductulator offers you a wide range of rectangular duct diameters that will create this when you enter those criteria. It also displays the required diameter for a circular duct. The actual instrument is constructed of sturdy, thick paper, and it contains a rotating piece that lets you select the two settings I previously indicated.
Random errors will shift each measurement from its true value by a random amount and in a random direction. These will affect reliability (since they're random) but may not affect the overall accuracy of a result.
From the question given, we were told that 0.1240 kg of propane reacted with excess oxygen to produce 0.3110kg of carbon dioxide.
Since the reaction took place in the presence of excess oxygen, therefore, propane is the limiting reactant as all of it is used up in the presence of excess oxygen.
