A company owns a refrigeration system whose refrigeration capacity is 200 tons (1 ton ofrefrigeration = 211kJ/min), and you are to design a forced-air cooling system for fruits whose diameters do not exceed 7 cm under the following conditions: The fruits are to be cooled from 28°C to an average temperature of 8°C. The air temperature is to remain above –2°C and below 10°C at all times, and the velocity of air approaching the fruits must remain under 2 m/s. The cooling section can be as wide as 3.5 m and as high as 2 m. Assuming reasonable values for the average fruit density, specific heat, and porosity (the fraction of air volume in a box), recommend reasonable values for the quantities related to the thermal aspects of the forced-air cooling, including (a) how long the fruits need to remain in the cooling section; (b) the length of the cooling section; (c) the air velocity approaching the cooling section; (d) the product cooling capacity of the system; (e) the volume flow rate of air; and ( f ) the type of heat exchanger for the evaporator and the surface area on the air side. |

Out of Li, C and N which one forms the most basic oxide and which one forms the most acidieoxide? |
|
Answer» Answer: Li will FORM the most basic oxide and N will form the most ACIDIC oxide Explanation: this is because Li is basic in nature. it releases OH- ions when it COMES in contact with water. Li²O is a basic oxide. similarly, N is acidic in nature. it releases H+ ions when it is dissolved with water. NO or NO² is an acidic oxide. I hope this HELPS. mark me as a BRAINLIEST. |

Give reaons:(a) Fennec Fox have very large ears.(b) Camel has thick and leathery patches on knees. |
|
Answer» (a) The fennec may be the world's smallest fox, but it sports outlandishly large ears! In fact, relative to body SIZE, it has the largest ears of any member of the canid family. It uses those big ears to listen for sounds of PREY in the sand. The ears also help dispel body heat to keep the fox cool. (b) The fur reflects the SUNLIGHT, which helps keep the animal cooler by day. Thick PATCHES of dry SKIN appear on a camel's chest and knee joints when the animal reaches five months of age. These leathery patches help support the animal's body weight when kneeling, resting and rising. Hey sisò Good afternoon.... |

सही उत्तर पर चिन्ह । लगाइए।यदि लोहे की कीलों को कुछ देर तक कॉपर सल्फेट के विलयन में रखा जाए तो(a) लोहे की कीलों का रंग भूरा हो जाता है।(b) लोहे की कीलें अप्रभावित रहती हैं।(८) भरे रंग की गैस निकलती है। |
|
Answer» जब लोहे की कील को कॉपर सल्फेट के विलयन में डुबोया जाता है तो विलयन का रंग नीले (CUSO4)से बदलकर हरा (FESO4) हो जाता है क्योंकि लोहा कॉपर की अपेक्षा अधिक सक्रिय धातु है। यह कॉपर सल्फेट के गोल में से कॉपर को विस्थापित करने की क्षमता रखता है तथा आयरन सल्फेट विलयन बनता है। |

The speed of light in transparent medium is 2.4 x 10⁸ m/s. Calculate absoluterefractive index of the medium. |
|
Answer» ANSWER:The REFRACTION index, n, of a TRANSPARENT medium is defined as the ratio of speed of light in VACUUM to the speed of light in that medium. The FORMULA is n= v c . where the speed of light c=3×10 8 m/s and v is the speed of light in the desired medium which is given as v=2.4×10 8 m/s. Therefore, n= 2.4×10 8 m/s 3×10 8 m/s =1.25. Hence, the refractive index of the transparent medium is 1.25 Explanation: |

The standard unit of measurement of distance or length in metric system is miles.2. Meterstick, tape measure, and sturdy rope are some of the standard tools in measuringdistance.3. Yard, foot, and inch are units of measurement used in the metric system of measurement.4. The measure of how far or near two points are from one another is called distance.5. The metric system of measurement of distance is used only in the Philippines.6. In science, distance should always be exact, measured accurately, and based on any unit ofmeasurement.7. The English system of measurement is used by scientists throughout the world.8. Using different units of measurement may lead to misunderstanding and confusion amongpeople.9. Ten kilometers is equal to 1000 meters.10. Speed can be calculated by multiplying the distance covered by an object in motion by theamount of time it used to cover the distance. |

To determine the pHof the givenzampley using pH paper or Universalindicatorwhat is the aim |
|
Answer» The nature of the chemicals used in laboratories is either basic, acidic or neutral. This characteristic depends on the ions they RELEASE. A CHEMICAL is said to be acidic if it releases H+ ions in its aqueous solutions. A chemical is said to be basic if it releases OH– ions in its aqueous solutions. In this experiment, we will learn how to find the pH of acids and bases. Aim: To determine the pH of the given SAMPLES using pH paper or universal indicator. The samples whose pH has to be determined are- Dilute CH3COOH Dilute NaOH Salt NaCl Dilute NaHCO3 Water Lemon juice Materials required: Six test tubes Test tube stand Dilute acid CH3COOH Dilute base NaOH Salt NaCl (preparation: dissolve 1 gram salt in 10 mL distilled water) Water Lemon juice Dilute NaHCO3 Glass rod Measuring cylinder (10 mL) STANDARD pH colour chart pH paper Glass rod Dropper Universal indicator Theory: What is pH? pH is a measure of hydrogen ion concentration to determine the alkalinity or acidity of a solution. If the pH value of a solution is less than 7 it is an acidic solution If the pH value of a solution is greater than 7 it is a basic solution If the pH value of a solution is equal to 7 it is a neutral solution What is pH scale? The pH scale consists of VALUES which range from 0 (very acidic) to 14 (very alkaline). The numbers on the scale help to determine the hydrogen ion concentration. What is pH paper? pH paper can help us know if a solution is basic, acidic or neutral. When the pH paper is dipped into a solution whose pH has to be determined, a colour will be developed. This colour is compared with the standard pH colour chart. Instead of pH paper, we can also use universal indicator paper or universal indicator solution. What is universal indicator? A universal indicator is a mix of pH indicator solutions that are designed to determine the pH of solutions over a wide range of values. Put a drop of solution on the universal pH indicator paper. The colour developed on the paper is matched with the standard pH colour chart. |
