How do you calculate the area of a Venturi meter? Venturi Flow Equation and Calculator Preview: Venturi Flow Calculator. and. Therefore: and. Qmass = ρ · Q. Where: Q = volumetric flow rate (m3/s, in3/s) Qmass = Mass flowrate (kg/s, lbs/s) A1 = area = Π · r2 (mm2, in2) A2 = area = Π […]
Is soda is a mixture?
Is soda is a mixture? Soda is considered a heterogeneous mixture. It contains water, sugar, and carbon dioxide, which forms bubbles. While the sugar, water, and flavorings may form a chemical solution, the carbon dioxide bubbles are not uniformly distributed throughout the liquid. Is Salt a mixture? Ordinary table salt is called sodium chloride. It […]
How did Tilly know it was a tsunami?
How did Tilly know it was a tsunami? “What’s a tsunami?” her mother asked. Tilly explained that she had learned about tsunamis at school a few weeks ago. “They are strong waves caused by undersea earthquakes,” she said. “And they travel very fast. How did Tilly become aware of the upcoming calamity? Tilly had become […]
How long do lead aprons last?
How long do lead aprons last? 10 years How often should lead aprons be checked? Lead aprons should be checked fluoroscopically at least on an annual basis for their shielding integrity. Rejecting an apron depends on the location, area size and number of flaws. It is best to keep the number of flaws to a […]
How do birds stay in the air?
How do birds stay in the air? Flapping: When birds flap, the stroke of their downbeat moves the wing tips forward and downward. And as they move forward, the rush of air on their airfoil wings causes more lift. But because flapping birds have smaller wings than soaring birds, they must move forward faster to […]
How much force does it take to break an egg from end to end?
What causes the partial negative charge in water?
What causes the partial negative charge in water? Polarity of water molecules A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This gives the oxygen end of the water molecule a partial negative charge, while the hydrogen end has a partial positive charge. Why does […]
What is the difference between remote control and radio control?
What is the difference between remote control and radio control? There is a simple definition for both remote-controlled and radio-controlled. Essentially, a remote-controlled vehicle is operated from a distant or remote location outside of the vehicle. A radio-controlled vehicle is simply an unattached remote-controlled vehicle. How does a remote-controlled car work? Once the RC toy […]
What are 3 facts about the mesosphere?
What are 3 facts about the mesosphere? The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), are found near the […]
Which graph is used to show change in a given variable?
Which graph is used to show change in a given variable? line graph What are variables in a chart? Variables control charts are used to evaluate variation in a process where the measurement is a variable–i.e. the variable can be measured on a continuous scale (e.g. height, weight, length, concentration). Which graph would be best […]
