What happens when thermosets are heated? Thermoset polymers do not soften when heated because the molecules are cross-linked together and remain rigid. The chemical bonding formed within a polymer, and the shape of the resulting polymer, affect its properties. Which is thermosetting polymer? A thermosetting polymer, resin, or plastic, often called a thermoset, is a […]
What are the different losses that occur in a steam turbine?
What are the different losses that occur in a steam turbine? Losses due to leakage :- In Impulse turbine, leakage loss occurs between the shaft, bearings, nozzles and stationary diaphragms. For Reaction turbine, it may occur at the blade tips. This loss is due to the leakage of steam on each stage of the turbine. […]

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 […]
What is the difference between a hypothesis and a prediction quizlet?
What is the difference between a hypothesis and a prediction quizlet? The difference between a hypothesis and a prediction is that a hypothesis is a proposed explanation for a set of observations; it leads to predictions that can be tested by additional observations or by experiments. A prediction is a guess of what might happen […]
