What is critical radius of insulation explain its importance in electrical and thermal system? The critical radius of insulation is a counterintuitive concept within the study of heat transfer. The theory states that adding insulation to a cylindrical or spherical object will increase the rate of heat loss rather than decrease it, if the radius […]

What happens if the piston ring gap is too wide?
What happens if the piston ring gap is too wide? Now, if the gap is too big, the engine will have too much crankcase pressure, have a ton of blow-by, burn oil, and lack proper cylinder sealant. Different engine setups need different piston ring gaps and it’s mostly dependent on how much fuel is being […]
Which stroke of the four-stroke cycle is shown in the figure above?
Which stroke of the four-stroke cycle is shown in the figure above? Answer Expert Verified The Exhaust stroke. The exhaust stroke is the final stroke of the four-stroke cycle engine. It occurs when the stroke valve is open and the intake valve is closed as can be seen in the picture above. Which strokes make […]
What causes knock?
What causes knock? Knocking occurs when fuel burns unevenly in your engine’s cylinders. When cylinders have the correct balance of air and fuel, fuel will burn in small, regulated pockets instead of all at once. Engine knocking happens when fuel burns unevenly and those shocks go off at the wrong time. What causes knocking noise […]
What are other methods of determining water discharge?
What are other methods of determining water discharge? Examples of such structures include streams, rivers, irrigation ditches, canals, partially full pipes, and water conveyance flumes. Some of the more common methods currently in use to measure open channel flows are: Timed Gravimetric. Tracer-Dilution. How do you measure the flow rate of a river? In the […]
What is the purpose of daytime running lights?
What is the purpose of daytime running lights? Fundamentally, DRLs are bright, low powered lights usually using LED technology, which operate all the time that your car is running – a sight now commonplace on British roads. The purpose is simple, to make it easier for other road users such as pedestrians, cyclists, and cars […]
How do you measure latent heat of steam?
How do you measure latent heat of steam? Determination of Latent Heat of Steam by the Method of Mixture A calorimeter with stirrer is taken and it is weighted. Some water is poured into a calorimeter then mass and temperature of a stirrer, calorimeter and water is taken. Steam is generated in a steam generator […]
How can bearing failure be prevented?
How can bearing failure be prevented? Consider these six actions you can take now to prevent a bearing — and process — failure. Choose the correct bearing design. Store bearings actively. Install bearings properly. Lubricate bearings according to manufacturers’ guidelines. Align machinery precisely. Balance equipment well. What can cause premature bearing failure? The principle causes […]
What is the ideal cycle for steam power plant?
What is the ideal cycle for steam power plant? Rankine cycle What is regeneration in steam power plant? To save fuel, efforts are constantly made to improve the efficiency of the cycle on which steam power plants operate. This process is called regeneration and the heat exchanger where heat is transferred from steam to feedwater […]
