How do you find slope angle of a river? The gradient of a river is a measure of how steeply it loses height. It is measured using a clinometer over a 10m stretch of the river. Ranging poles mark out the stretch of river. The clinometer is placed against the height mark on one pole […]
What is a typical Reynolds number?
What is a typical Reynolds number? turbulent flow occurs over a range of Reynolds numbers from approximately 2,300 to 4,000, regardless of the nature of the fluid or the dimensions of the pipe or the average velocity. All that matters is that this specific combination of the parameters, known as the Reynolds number, fall in […]
What are the equivalent units of production conversion?
What are the equivalent units of production conversion? Equivalent units of production = units transferred out + equivalent units in ending work in process inventory − equivalent units in beginning inventory. Calculate the units of production from both materials and conversion. Using FIFO, you’ll have two percentages to determine for beginning and ending inventory. How […]
What is the physical arrangement of a network?
What is the physical arrangement of a network? Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data — the physical structure of the network […]
What are the 5 steps in adaptive immunity?
What are the 5 steps in adaptive immunity? Steps in adaptive immune process STEPS IN ADAPTIVE RESPONSE 1.Monocytes “eat” pathogen 2. Reveals part of antigen on cell surface 3. Receptor on helper T-cell identifies the antigen 4. STEPS IN ADAPTIVE RESPONSE 5. Killer T-cells become activated to attack specific pathogen 6. B-cells become activated and […]
Are all new furnaces High Efficiency?
Are all new furnaces High Efficiency? In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust. High efficiency furnaces offer 90% or more AFUE. These days, 95% AFUE is a common rating among new gas-powered furnaces. So a 95% furnace is more efficient than an 80% furnace. What […]
How is capillary effect affected by the contact angle?
How is capillary effect affected by the contact angle? Capillary action can also be to understood in terms of capillary pressure. Pcap = 2 γlv *cos(θ) / r. From this, we see that the lower the contact angle (the more hydrophilic the pore) the higher the capillary pressure and thus the the stronger the capillary […]
What are the main parts of a clutch assembly?
What are the main parts of a clutch assembly? The modern clutch has four main components: the cover plate (which incorporates a diaphragm spring), the pressure plate, the driven plate, and the release bearing. What parts are included in a clutch kit? Summary. A clutch kit is a selection of parts that are used to […]
How does dislocation affect the mechanical properties?
How does dislocation affect the mechanical properties? Dislocations interact with each other by generating stress fields in the material. The interaction between the stress fields of dislocations can impede dislocation motion by repulsive or attractive interactions. Why are dislocations important in metals? Dislocations play an essential role in the plastic deformations of crystalline materials. They […]
What does the knock sensor do?
What does the knock sensor do? The engine’s knock sensor (or sensors) detects preignition and detonation, potentially damaging forms of abnormal combustion. Though full-blown knocking and pinging are audible to the human ear, the knock sensor detects imperceptible levels. What voltage does a knock sensor produce? 4.5 volts What does a knock sensor measure? Knock […]
