How do you calculate dry solids? Divide the mass of solids by the total mass of the solution, and then multiply the result by 100 to calculate the percentage of solids by weight. In this example, (17/167) * 100 = 10.18 percent. What is meant by volatile solids? Volatile solids are a substance that can […]
How do you calculate the transfer function of a DC motor?
How do you calculate the transfer function of a DC motor? Transfer Function of Armature Controlled DC Motor Let Ra = Armature resistance, La = Armature inductance. Ia = Armature current. Va = Armature voltage. eb = Back emf. Kt = Torque constant. Kb= Back emf constant. What is field controlled DC motor? Field Controlled […]
What controls the size of the arc in welding?
What controls the size of the arc in welding? Amperage How electric arc is produced in welding? An arc is an electric current flowing between two electrodes through an ionized column of gas. A negatively charged cathode and a positively charged anode create the intense heat of the welding arc. Negative and positive ions are […]
What do you mean by thermal boundary layer How does the ratio of velocity boundary layer thickness to thermal boundary layer thickness vary with Prandtl number?
What do you mean by thermal boundary layer How does the ratio of velocity boundary layer thickness to thermal boundary layer thickness vary with Prandtl number? The thermal boundary layer thickness is similarly the distance from the body at which the temperature is 99% of the freestream temperature. The ratio of the two thicknesses is […]

The government-backed effort includes a fleet of six Ford Mondeos outfitted by autonomous tech developer Oxbotica and its partners. What is the most autonomous car available? 2020 […]
Which pairs are considered as lower pairs?
Which pairs are considered as lower pairs? The sliding pairs, turning pairs and screw pairs form lower pairs. Explanation: When the two elements of a pair have surface contact when relative motion, takes place and the surface of one element slides over the surface of the other, the pair formed is known as lower pair. […]
What is the advantage of using a chain sprocket over spur gears?
What is the advantage of using a chain sprocket over spur gears? *The advantage of a chain drive that uses sprocket gears over using spur gears is the ability to transfer torque and speed over longer distances. What is the advantage of using a chain drive over a belt drive? Highly efficient, chain drives gives […]
What is the slenderness ratio of compression member?
What is the slenderness ratio of compression member? What is slenderness ratio of compression member? Explanation: The tendency of member to buckle is usually measured by its slenderness ratio. Slenderness ratio of member is ratio of effective length to appropriate radius of gyration (λ = kL/r). What is the slenderness limits for column? 6.35a reduces […]
