How do you increase thrust? The most widely recognized method of boosting thrust is the afterburner, also known as tailpipe burning. Fuel is injected into the hot exhaust gas flowing between the turbine and nozzle. The combustion of the gas expands the airflow as it enters the nozzle, which increases thrust. Does thrust increase lift? […]
What is an oil additive give any two additive?
What is an oil additive give any two additive? Controlling chemical breakdown Typical detergents are magnesium sulfonates. Corrosion or rust inhibiting additives retard the oxidation of metals inside an engine. Antioxidant additives retard the degradation of the oil stock by oxidation. Typical additives are organic amines and phenols. What are oil additives? Motor oil additives […]
What are the two types of fluid flow?
What are the two types of fluid flow? Types of Fluid Flow Fluid flow is generally broken down into two different types of flows, laminar flow and turbulent flow. Laminar flow is fluid motion in which all the particles in the fluid are moving in a straight line. Why is fluid flow important? Fluid dynamics […]
Why is it important to know if a mechanism has a single degree of freedom?
Why is it important to know if a mechanism has a single degree of freedom? Problem 3.2 Solution: a) Because the DOF of a mechanism is the number of mechanism parameters required to fully define its motion, a mechanism having a single DOF requires a single mechanism motion parameter to fully define mechanism motion. As […]
What is the best engine temperature?
What is the best engine temperature? between 195 degrees and 220 degrees What temperature will damage an engine? As temperature of an engine exceeds 230 degrees Fahrenheit, the engine is overheated. Above 245 degrees Fahrenheit, damage may occur. What temperature should engine oil run at? A quality conventional motor oil will tolerate oil sump temperatures […]

What are the advantages and disadvantages of centrifugal pump?
What are the advantages and disadvantages of centrifugal pump? Centrifugal Pump – Advantage & Disadvantage Small in size, space saving & less capital costs. Easy for maintenance. No danger creates if discharge v/v is closed while starting. Deal with large volume. Able to work medium to low head. Able to work medium to low viscous […]
What is springback in sheet metal bending?
What is springback in sheet metal bending? Springback is ever-present in sheet metal forming. The bending angle is the beginning angle to which the operator overbends so that the metal springs back to the desired bent angle. Springback occurs when the material angularly tries to return to its original shape after being bent. Does the […]
Which of the electromagnetic waves below has the largest wavelength?
Which of the electromagnetic waves below has the largest wavelength? Radio waves have the longest wavelength, and gamma rays have the shortest wavelength. Which frequency has the largest wavelength? The electromagnetic spectrum ranges from gamma (γ) radiation, which has the shortest wavelength, highest frequency, and greatest energy, to radio waves, which has the longest wavelength […]
How do you find the heat capacity of a calorimeter?
How do you find the heat capacity of a calorimeter? Part I: Heat Capacity of the Calorimeter The heat capacity, C, of a substance is the amount of heat required to raise the temperature of a given quantity of the substance by 1 degree. The relationship between heat capacity and specific heat is C = […]
