The specific weight (wt./vol.) of brass is 85 kN/m^3. Determine its density (mass/vol.) in SI units. Use an appropriate prefix.
A five-cylinder, 3.5-liter SI engine operates on a four-stroke cycle at 2500 RPM. At this
condition, the mechanical efficiency of the engine is 62% and 1000 J of indicated work are
produced each cycle in each cylinder.
Calculate:
Brake power in kW and hp.
Torque. [N-m]
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

- A commonly used unit in everyday language to state weight is the pound (lb). There are actually several formal definitions of pound. One classification system defines a pound-mass (analogous to kg in SI units) and a pound-force (lbf) (analogous to a Newton); this is formally called English Engineering units but also commonly used in US Customary System units. The “pound” in the “pounds per square inch” of psi refers to pound-force. Hence, psi has units of force per area. Note that 1 lbf is defined as the gravitational force generated by 1 lb (mass) by multiplying it by the standard gravitational acceleration at the earth’s surface. Starting with just the two everyday conversion approximations every Canadian should know (1.00 kg ≈ 2.20 lb (mass) and 1.00 inch ≈ 2.54 cm), derive an approximation of 1.00 psi in Pa through unit conversions only (show each step).arrow_forwardshear stress at the plate boundary and at y = 0.15 m from the plate.

P = pressure, V = volume, n = number of moles of ideal Gas, R = General gas constant = 8.314 kJ/(kmol.K) and T = absolute temperature. 5 mol ideal gas at 22°C is placed in a cube with edge lengths of 0.750 meters.

Assume that the aerosol can is unable to withstand pressures in excess of 3 bar show cancellation of units and formula usedarrow_forwardSome scientists believe that the collision of one or more large asteroids with the Earth was responsible for the extinction of the dinosaurs. The unit of kiloton is used to describe the energy released during large explosions. It was originally defined as the explosive capability of 1000 tons of trinitrotoluene (TNT) high explosive. Because that expression can be imprecise depending on the explosive's exact chemical composition, the kiloton subsequently has been redefined as the equivalent of 4.186 x 1012 J. In the units of kiloton, calculate the kinetic energy of an asteroid that has the size (box-shaped, 13 x 13 x 25 km) and composition (density, 2.4 g/cm) of an asteroid. Kinetic energy is defined by U. = mv? where m is the object's mass and v is its speed. Objects passing through the inner solar system generally have speeds in the range of 20 km/s.
