What is the temperature maintained in cold storage? The International Institute of Refrigeration recommends a storage temperature of -18°C for lean fish such as cod and haddock and -24°C for fatty species such as herring and mackerel. The code also recommends that for lean fish intended to be kept in cold storage for over a […]
What is the basic ingredient of ceramics?
What is the basic ingredient of ceramics? Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known […]
What do you mean by fouling factor What are the causes of fouling?
What do you mean by fouling factor What are the causes of fouling? The fouling factor represents the theoretical resistance to heat flow due to a build-up of a layer of dirt or other fouling substance on the tube surfaces of the heat exchanger, but they are often overstated by the end user in an […]
Is specific entropy an intensive property?
Is specific entropy an intensive property? Entropy (as the extensive property mentioned above) has corresponding intensive (size-independent) properties for pure materials. A corresponding intensive property is specific entropy, which is entropy per mass of substance involved. Why is entropy an extensive property? An extensive property is dependent on size (or mass), and like you said, […]
What is salvage ethnography quizlet?
What is salvage ethnography quizlet? Salvage Ethnography. The recording of the practices and folklore of cultures threatened with extinction, including as a result of modernization. It is generally associated with the American anthropologist Franz Boas; he and his students aimed to record vanishing Native American cultures. Urgent Anthro. What is the term for cultural change […]
How do you find the secondary current of a 3 phase transformer?
How do you find the secondary current of a 3 phase transformer? the following figure presents a nameplate of a three phase transformer…. Secondary voltages or Low Voltages (L.V) is 415 volts. Secondary Current (Current on Low voltages side) is 139.1 amps. KVA = (√3. V x I) /1000= (1.732 × 415 × 139.1)/1000=100 KVA. […]
What is a TPMS relearn procedure?
What is a TPMS relearn procedure? A relearn refers to the process of electronically pairing a new TPMS sensor to the vehicle’s Tire Pressure Monitoring System. A TPMS relearn is always required when a new TPMS sensor or sensors are installed. TPMS Vehicle relearn procedures vary by automaker. Some vehicles relearn automatically when you drive […]
How do you determine if a system is stable or unstable?
How do you determine if a system is stable or unstable? When the poles of the closed-loop transfer function of a given system are located in the right-half of the S-plane (RHP), the system becomes unstable. When the poles of the system are located in the left-half plane (LHP) and the system is not improper, […]

Glass Transition Temperature of some Polymers Polymer Tg (K)a,b Polypropylene (PP) 260 (239) Polyethylene (HDPE)* 148* (148, 186, 238) Polymethylacrylate (PMA) 283 (285) Polypropyleneglycol (PPG) 198 (205) Is coconut oil a plasticizer? 18.3. Plasticizer contains fatty acid, which has the ability to stretch rubber […]
What is tubular heat exchanger?
What is tubular heat exchanger? Tubular heat exchangers is the collective term for a wide variety of heating systems to heat water thermal oil, glycol, crude oil, gas, air for combustion and are also used in biogas reheating and steam production. How do you calculate pressure drop in a heat exchanger? Since the pressure drop […]
