- Suppose we got the following data during a test of a 2- stroke engine in which gas is usedas a fuel:Diameter of the piston = 149 mmStroke length = 179 mmClearance volume = 0.88 literrpm of the engine = 302Indicated mean effective pressure = 6.0 barGas consumption = 6.0 m3/hCalorific value of the gas (fuel) = 16990 kJ/m3Make a clear sketch the geometry of this engine using the data and determine thefollowing:i. Indicated power developed by the engine in watt.ii. Air Standard Efficiencyiii.

Sunco estimates that eachdistribution point can sell up to 5 million barrels per year.Because of differences in shipping and refining costs, theprofit earned (in dollars) per million barrels of oil shippeddepends on where the oil was refined and on the point ofdistribution (see Table 51). Sunco is considering expandingthe capacity of each refinery. Each million barrels of annualrefining capacity that is added will cost $120,000 for the LosAngeles refinery and $150,000 for the Chicago refinery. Uselinear programming to determine how Sunco can maximizeits profits less expansion costs over a ten-year period.
- Please show the complete solution. (Example: Conversion of Units) How much heat in kJ must be transferred to 20 kg of air to increase the temperature from 20 Degree Celsius to 280 Degree Celsius if the pressure is maintained constant?The horizontal force due to water acting on the bolt (Fh): Fh=ρ×A1×V1×V1--V2 Fh=1000×π4×0.0752×1.254×1.254+11.286( Fh)=69.472 This is the only part I did not understand how to get. Can you please explain more? I arrived with this equation, -P1A1 - P2A2 (cancelled since atmos. Pres.) +Fh = rho A1v1 (v2-v1) Why did P1A1 disappear in your solution? How did you come up with (v1 - - v2) ? What is the control volume? Why did you not do a summation of forces is equal to change in momentum but instead go immediately to getting the horizontal force acting on the bolt?#01: Explain the following terms in your own words. a) Aerodynamics. b) Mach Number. c) Sub-Sonic. d) Angle of Attack. e) Thrust. f) Chord Line. g) Drag Coefficient. h) Pitch Moment. i) Wind Tunnel. j) Skin Drag.
- Hello im reviewing my notes and im confused as to how s and n were able to come up with the equation. Please help. n=(cos30,sin30,0) s=(-cos60,sin60,0) Please explain,thank you9.16. One kind of thermodynamic diagram that is useful in engineering problems is the P–H diagram, in which the x-axis is molar enthalpy and the y-axis is pressure.(a) Several kinds of iso-lines can be drawn in such a diagram, including isotherms(constant temperature), isentrops (constant entropy), and isochores (constant molar volume). For each of these three cases, find expressions for the slope of these lines on a P–H diagram in terms of measurable properties.(b) Find expressions for these slopes for the ideal monatomic gas, in terms of T and P. Explain on physical grounds any unusual resultsDuring a mountain climbing trip it is observed that the water used to cook a meal boils at 93 °C rather than the standard 100 °C at sea level. At what altitude are the climbers preparing their meal? (See Physical Properties of Water (SI Units) and Properties of the U.S. Standard Atmosphere (SI Units) for data needed to solve this problem.) Wiley saids the answer is 2059.7m. I'd appreciate it if somebody would work it out for me
- a) The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a 54.9C temperature increase? (b) Compare your answer to labeling information found on a package of peanuts and comment on whether the values are consistent.The p-v diagram all make sense, but the equations are unreadable. i dont understand where some units have come from etc, could you please further explain the equations. thnks, feel free to take the relevant amount of creditsExpand the following terms into expressions with variables that can be measured experimentally such as pressure, temperature, volume, Cv, and Cp. Two of the below expressions will result with S in the final expression:A) (∂A/∂S)PB) (∂A/∂S)TC) (∂G/∂P)S
