1. Complete the tables below with your measurements and determinations of the humidity variables inside andoutside of the Engineering Building. In the first blank column of the table (titled Individual Measurement) fill in theboxes for the temperature and wet-bulb temperature. Average values of the temperature and wet-bulb temperaturefor all the measurements taken by everyone in the class will be used to complete the last column of the table (titledAverage Measurement). Use the temperature and wet-bulb temperature values and the average values of thesetemperatures in the last column, to determine the remaining humidity variables, using the psychrometric chart.Inside the Engineering BuildingHumidity VariableIndividual MeasurementAverage Measurement ofGroupT (°C) (measured)Tw (°C) (measured)Ta (°C)Vapor Pressure: e (mb)Dew-point Depression (°C)Relative Humidity (%)Outside the Engineering BuildingHumidity VariableAverage Measurement ofGroupIndividual MeasurementT (°C) (measured)Tw (°C) (measured)|Ta (°C)Vapor Pressure: e (mb)Dew-point Depression (°C)Relative Humidity (%) Outside the building:Dry-bulb temp = 30°C or 86°FWet-bulb temp = 18°C or 84°FInside the building:Dry-bulb temp = 21°C or 70°FWet-bulb temp = 16°C or 61°FNote: Dew-point depression is T- Td

Van der Waals bonding is generally stronger than covalent bonding d. The free electrons in metallic bonding is reason for electrical conductivity 8. Which of the following is true: a. Polymers are generally denser than ceranmics b. Young's modulus of ceramics are similar to polymers c. Composites have higher tensile strength than metals d.

Calorimeters are devices that are commonly used to measure the heating value of fuels. For example, a Junkers flow calorimeter is used to measure the heating value of gaseous fuels. A bomb calorimeter, on the other hand, is used to measure the heating value of liquid or solid fuels, such as kerosene, heating oil, or coal. Perform a search to obtain information about these two types of calorimeters. Write a brief report discussing the principles behind the operation of these calorimeters.
What’s the correct answer please?
ENGINEERING MATERIALS
1-heat is defined as the average kinetic energy of the atoms and molecules that make up a substance and temperature is the amount of thermal energy transported2- heat is defined as the total kinetic energy of the atoms and molecules that make up a substance and temperature is the transport of pressure energy due to the temperature gradient3- Heat is defined as the average kinetic energy of the atoms and molecules that make up a substance and temperature is a measure of the equivalent kinetic energy of the individual molecules or atoms4- Heat is defined as the total kinetic energy of the atoms and molecules that make up a substance and temperature is a measure of the total kinetic energy of the individual molecules or atoms5- Heat is defined as the total kinetic energy of the atoms and molecules that make up a substance and temperature is a measure of the average kinetic energy of the individual molecules or atoms choose only one of the above alternatives as correct

As we explained in earlier chapters, the air resistance to the motion of a vehicle is something important that engineers investigate. The drag force acting on a car is determined experimentally by placing the car in a wind tunnel. The air speed inside the tunnel is changed, and the drag force acting on the car is measured. For a given car, the experimental data generally is represented by a single coefficient that is called drag coefficient. It is defined by the following relationship: F, where air resistance for a car that has a listed C, = drag coefficient (unitless) measured drag force (N) drag coefficient of 0.4 and width of 190 cm and height of 145 cm. Vary the air speed in the range of 15 m/s

QUESTION 2 Thermocouples are devices used to measure temperature of a given sample or the surrounding medium. These devices feature a "bead", which has a spherical shape, and produces voltage upon change in temperature. For an engineering application at a pharmaceutical company, thermocouple devices are being tested for their responsiveness, i.e. how fast it can detect temperature changes in the environment (surrounding air). The engineers at this company have specified design constraints for an ideal thermocouple: it must detect temperature changes no later than 1.5 minute, and the reported temperature value must be reasonably correct: at most %3 difference between measured and actual temperature values is allowed. Four thermocouples from different vendors are being tested. Relevant properties of these devices are listed below: Thermal conductivity Density 36 W/m*K 36 W/m*K 42 W/m*K 33 W/m*K Specific Heat 140 kJ/kg*K 120 kJ/kg*K 150 kJ/kg*K 160 kJ/kg*K Device Bead Diameter…
