- Mechanical Engineering The following equation is used to calculate a change in the kinetic energy of a moving mass: KE = 0.5 * m * (v2 - u2) Where the quantities are: the kinetic energy KE (in Joules), the mass m (in kg), the initial velocity u (in m/s) and the final velocity v (in m/s). Determine if the equation is dimensionally homogeneous or not.
*arrow_forward*One can change the system energy by work (W) and by heat transfer (Q). In a closed system, this is described by the following relation: AE = Q - W Enter the SI units (abbreviated as expected, for example, m instead of meter) for Q and W in the following format: X, X*arrow_forward*How much heat is absorbed by a 27.0 g sample of water in going from liquid at 38.2 °C to steam at 119 °C and a pressure of 1.00 atm? Use the data in the following table. Express your answer in kilojoules. Pay attention to units!

For what values of m is the oscillator overdamped?
*arrow_forward*The "standard" acceleration (at sea level and 45° latitude) due to gravity is 32.2 ft/s². What force is needed to hold a mass of 8.0 kg at rest in this gravitational field? [express your answer in SI unit with two decimal places]*arrow_forward*Q4/ An orifice meter is used to measure the rate of flow of a fluid in pipes. The flow rate is related to the pressure drop by the following equation: |ΔΡ u = c where u = fluid velocity AP = pressure drop (force per unit area) p = density of the flowing fluid C = constant What are the units of c in the SI system of units?*arrow_forward* - Q1: Apply appropriate solution method using math principles to prove that "the pressure at a point in a fluid has the same magnitude in all directions". Support your answer with sketch. Answer: Px Pz = Pn P are the mean pressures at the three surfaces in the x- and z-directions. Q2: Formulate the issue and identify key variables to prove that [AP = P2 - P, = pg Az = y, Az], where y, and p are the specific weight and density of the fluid, respectively. Az is the vertical distance. Support your answer with sketch. Q3: From fluid mechanics science perspective, define the center of gravity and the center of pressure.

*arrow_forward*Q1. The image below shows an example of "absolute dependent motion analysis", where the motions of two objects depend on each other, and the goal is to find the relations in their motions (i.e., in their positions, velocities, and accelerations). Please put the suggested steps of analysis in the correct order. VA A B VB Differentiate the entire equation with respect to time, and extract the relation in velocities. Repeat for acceleration if needed. Set up a coordinate (s) along the direction of motion from a fixed point (O) or a fixed datum line. Represent the positions of the objects respectively. In some cases intermediate objects need to be considered too and their positions need to be represented as well. Recognize the constant length(s) and find the depending geometric relations between the position variables.*arrow_forward*As the temperature of the hydrogen gas decreases of same gas decreases.

In an old heat transfer textbook, you found the following equation for some specific heat transfer problem. Ə²T Q + əx² λ ƏT Ət You know that T is temperature (K) and x is the x-coordinate, which is measured in meters. You also know that t is time (s) and the book uses as the symbol for thermal conductivity, whose unit is W/m.K. What must be the units of Q and B?*arrow_forward*
