Task 2: Comparable Interface and Record (10 Points) 1. You are tasked with creating a Java record of Dog (UML is shown below). The dog record should include the dog's name, breed, age, and weight. You are required to implement the Comparable interface for the Dog record so that you can sort the records based on the dogs' ages. Create a Java record named Dog.java. name: String breed: String age: int weight: double + toString(): String > Dog + compareTo(otherDog: Dog): int > Comparable 2. In the Dog record, establish a main method and proceed to generate an array named dogList containing three Dog objects, each with the following attributes: Dog1: name: "Buddy", breed: "Labrador Retriever", age: 5, weight: 25.5 Dog2: name: "Max", breed: "Golden Retriever", age: 3, weight: 30 Dog3: name: "Charlie", breed: "German Shepherd", age: 2, weight: 22 3. Print the dogs in dogList before sorting the dogList by age. (Please check the example output for the format). • 4. Sort the dogList using…
As shown in the figure below, moist air at T₁ = 36°C, 1 bar, and 35% relative humidity enters a heat exchanger operating at steady state with a volumetric flow rate of 10 m³/min and is cooled at constant pressure to 22°C. Ignoring kinetic and potential energy effects, determine: (a) the dew point temperature at the inlet, in °C. (b) the mass flow rate of moist air at the exit, in kg/min. (c) the relative humidity at the exit. (d) the rate of heat transfer from the moist air stream, in kW. (AV)1, T1 P₁ = 1 bar 11 = 35% 120 T₂=22°C P2 = 1 bar
2. A moving bed adsorption column needs to be designed to separate hydrophobic proteins from a fermentation broth. The following adsorption equilibrium data was observed in preliminary isotherm studies. The resin used was activated carbon with a porosity of 0.2. The overall mass transfer coefficient was determined to be 10 h¹, and the ratio of volumetric flow rate of broth to resin is 10. Determine the diameter of the column if the column height is limited to 2.5 m (indoor operation) with a flow rate of 20 m³/h, influent concentration of 7 g/L, and effluent concentration of 0.1 g/L. qi (mg/kg) Ci (g/L) 0.1 4.7 7.5 0.25 10.6 0.5 15.0 1.0 23.7 2.5 33.5 5.0 41.1 7.5
