How do you account for the BOD of seeded dilution water? #2 Seed BOD = (DO depletion x 300)/Seed dilution, mL The calculated seed BOD represents the BOD exerted by 300 mL of undiluted seed material. The ratio of the seed BOD to 300 mL will be used to calculate the seed correction for seeded […]
Why is the vector insert ratio important during ligation?
What role does forecasting play in the supply chain of a build to order?
What role does forecasting play in the supply chain of a build to order? From cutting costs to keeping consumers happy, forecasting is a vital component of supply chain management, helping companies fill orders on time, avoid unnecessary inventory expenses and plan for price fluctuations. What role does Forecast play in the supply chain of […]
What is the efficiency of a coal fired power plant?
What is the efficiency of a coal fired power plant? Typical thermal efficiency for utility-scale electrical generators is around 37% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.) […]
What does a product safety engineer do?
What does a product safety engineer do? Product safety engineers investigate the causes of accidents or injuries that might have resulted from the use or misuse of a product. They create solutions that reduce or eliminate safety issues associated with products. They also help design new products to prevent injuries, illnesses, or property damage. How […]
What is low refrigerant charge?
What is low refrigerant charge? Low refrigerant means low pressure and low pressure means low temperatures that will eventually freeze something called an evaporator coil. When the evaporator coil freezes, cold liquid refrigerant flows through the refrigerant line, causing the surrounding moisture in the air to freeze. Why is my air conditioner low on Freon? […]
Does entropy disprove evolution?
Does entropy disprove evolution? Since life has had 4 billion years to evolve on Earth, the theory of evolution does not appear to be threatened by the second law of thermodynamics. Far from threatening evolution, as we will see, entropy actually functions as a thermodynamic driving force behind natural selection. Does entropy mean decay? As […]
What is linear and angular momentum?
What is linear and angular momentum? In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant. What is momentum flow? momentum flow = (mass flow) […]
What is the specific gravity of electrolyte in a fully charged battery?
What is the specific gravity of electrolyte in a fully charged battery? 1.280 to 1.300 When checking the specific gravity of the electrolyte in a fully charged battery What would you expect the hydrometer to read? A fully charged battery will test at 1.275 – 1.280 while a discharged battery will read in the 1.140 […]
What is the product of current and resistance?
What is the product of current and resistance? Product of Current and Resistance gives Volt. As well Ohm’s law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). What is the product of voltage and current? Electrical power What is current […]
