What are the properties of air Grade 6? Let’s review everything we learned about air, or the mixture of gases, water vapor, and other materials. Air takes up space. Air is made of gases, including nitrogen, oxygen, water vapor, and other materials. Air exerts pressure. Air has weight. Air can be compressed. Air is affected […]
How strong is galvanized steel pipe?
How strong is galvanized steel pipe? The mechanical properties of this type of pipe varies according to the method of manufacturing. However, the typical yield strength is around 30,000 psi. What is galvanized steel pipe used for? Galvanized steel pipe is covered with a zinc material to make the steel pipe more resistant to corrosion. […]
What are the roles of structural engineer?
What are the roles of structural engineer? Structural Engineer Responsibilities: Prepare reports, designs, and drawings. Make calculations about pressures, loads, and stresses. Consider the strength of construction materials and select appropriately. Provide technical advice on safe designs and construction. Obtain planning and/or building regulations approval. What are the three primary duties of an engineer? Engineer […]
What gives the aircraft directional stability?
What gives the aircraft directional stability? Yawing or directional stability is the most easily achieved stability in aircraft design. The area of the vertical fin and the sides of the fuselage aft of the CG are the prime contributors that make the aircraft act like the well known weather vane or arrow, pointing its nose […]
What is the value of compressibility factor Z of a gas when I pressure is low II pressure is high?
How do you calculate output speed?
How do you calculate output speed? Calculating Output Speed Using Pulley Diameters and Input Speed RPM Output/RPM Input = Multiplication Factor. On a belt-driven fan the two primary speeds required are the RPM of the Motor and the RPM of the fan. Formula. RPM Input/RPM Output = Diameter Out/Diameter In. Formula. RPM Input/RPM Output = […]
What is the Carnot efficiency of heat engine operating between 400 C and 100 C?
What is the Carnot efficiency of heat engine operating between 400 C and 100 C? Thus, the Carnot efficiency of heat engine is 55.42% . How do you calculate temperature efficiency? Practice Convert the high and low temperatures from Celsius to Kelvin: Thot=540oC+273=813K. Tcold=20oC+273=293K. Determine the efficiency using the Carnot efficiency formula: η=[1−TcoldThot]×100%η=[1−293K813K]×100%=64% How do […]
What are thermoplastics and thermosetting polymers?
What are thermoplastics and thermosetting polymers? Most linear polymers and branched structure polymers with flexible chains are thermoplastics. This is in contrast to thermosetting polymers, which do not soften when heated due to strong covalent crosslinks. Thermoset polymers are generally harder and stronger than thermoplastics and have better dimensional stability. What is the structure of […]
How do you test load cells?
How do you test load cells? A load cell test is performed using a digital multimeter. The digital multimeter is connected between the positive signal wire and the negative signal wire of the load cell. The output between them should be equal or to a value specified in the datasheet. This is the test for […]
What type of reaction is CO2?
What type of reaction is CO2? Combustion reactions involve the reaction of a substance with oxygen gas (O2). It is often referred to as burning. The products of the reaction are oxides of the elements in the reactants. Hydrocarbon combustion leads to the formation of carbon dioxide gas and water vapor. Is C O2 CO2 […]
