maybe 1+8 (4+548) 4/6 4+4
Answer:
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.
Answer:
The bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.
Explanation:
Ionic bonds are those bonds that form between the ions of molecules. It is formed as a result of electrostatic attraction between the molecules or compounds. The ionic bonds that forms between ionic compounds are responsible for certain properties exhibited by them.
Ionic bonds hold the molecules of ionic compounds so tightly that it prevent ions from moving throughout the crystal, hence, a solid ionic compound is a poor conductor of heat and electricity.
Answer: Wind current
Explanation:
The wind current is the main driving force along with the water currents when one reaches to the seashore. The wind currents above surface of water generates due to the evaporation of water.
The strong wind currents can pull any animal or human walking or running near the sea shore. These currents bring the animal or human towards the sea.
Answer:
B.sugar solution
Explanation:
A sugar solution is not a compound.
Rather, the solution is a mixture and an impure substance.
- A compound is composed of two or more kinds of atoms or elements joined in a definite grouping .
- The properties of the compound is distinct from those of the individual atoms that makes them.
- Sugar solution is sugar and water
- It is made up of two compounds not chemically combined.
