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?Physical Properties: https://education.wiley.com/player/index.html#/res;url=https:%2F%2Feducation.wiley.com%2Fcontent%2FBergman_Fund_Heat_Mass_8e%2Febook%2Fepub%2F9781119353881%2FOPS%2Fa01.xhtml%23headda01 Mathematical Functions: https://education.wiley.com/player/index.html#/res;url=https:%2F%2Feducation.wiley.com%2Fcontent%2FBergman_Fund_Heat_Mass_8e%2Febook%2Fepub%2F9781119353881%2FOPS%2Fa02.xhtml%23headda01

- The processing of raw coal involves “washing,” in which coal ash (nonorganic, incombustible material) is removed. The article “Quantifying Sampling Precision for Coal Ash Using Gy’s Discrete Model of the Fundamental Error” (Journal of Coal Quality, 1989:33–39) provides data relating the percentage of ash to the volume of a coal particle. The average percentage of ash for six volumes of coal particles was measured. The data are as follows: Volume (cm3) 0.01 0.06 0.58 2.24 15.55 276.02 Percent ash 3.32 4.05 5.69 7.06 8.17 9.36 Using the most appropriate model, predict the percent ash for particles with a volume of 48 cm3. Round answer to three decimal places. * the answer i got was of 6.260 was wrongSaponification is a process wherein soap is added to a certain type of oil to produce grease. One such grease is said to have 75.7 % by volume oil and 24.3% by volume soap, wherein the oil and soap have densities 760 kgm/m3 and 6,250 kgm/m3, respectively. This kind of grease is sold by packs shaped like a sphere with a diameter of 20 cm for convenience. Calculate: a) the mass of oil per pack (kgm), b) the mass of soap per pack (kgm), c) the weight of each pack (kgf), d) the specific weight of grease (N/m3), e) will the grease float if it is placed in water whose density is 1000 kgm/m3? Explain.Over the ocean surface, the Bowen ratio is estimated to be about 0.2. Estimate the sensible heat and latent heat fluxes to the atmosphere, as well as the rate of evaporation, in millimeters per day, from the ocean surface, when the net radiation received just above the surface is 800W per m^2 , the heat flux to the water below 55 m is negligible, the rate of warming of the 55 m deep oceanic mixed layer is 0.12 deg. Celsius per day, and the sea surface temperature is 27deg. Celsius.
- 9.16. 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 resultsThe same engineer decides to look into rates of cooling for liquids toexperiment with different cooling solutions for servers. She finds thatthe rate of cooling for one liquid can be modelled by the equation:y = 48 × 0.99t(0 ≤ t ≤ 80)where y is the temperature of the liquid in degrees Celsius and t is thetime in minutes.(i) State whether the type of reduction for this model is linear orexponential. Describe how reduction rate differs between linear andexponential functions. (ii) Calculate the temperature when t = 20. [3](iii) Write down the scale factor and use this to find the percentagedecrease in the temperature per minute.
