- we will cover engineering economics. For now, using the Excel Helpmenu, familiarize yourself with the following functions. Create a simpleexample and demonstrate the proper use of the function.a. FV(rate, nper, pmt, pv, type)b. IPMT(rate, per, nper, pv, fv, type)c. NPER(rate, pmt, pv, fv, type)d. PV(rate, nper, pmt, fv, type)Suppose the annualized cost of purchasing, fuelling and maintaining a compacter truck is given by the following expression Annualized cost (Rs/year) = 10,50,000 + 21,000 V Where V is the volume of truck in m3. Suppose these trucks require three persons crew with labor charge Rs 45/hr including benefits. Calculate the total annual cost of truck and crew. If volume of truck is 15 m3, and calculate the cost of solid waste collection/tonne of wet waste.Problem 4The decay of chlorine in a distribution system follows first-order decay with a rate constant of 0.015 hr-1.

- Can I get a thorough step by step for this question? Each month the speedy dry-cleaning company buys 1.75 barrel (0.28 m') of dry-cleaning fluid. The amount of fluid lost to the atmosphere as emission is 210 kg/month and the remaining remains as residue to be disposed of. The density of the dry-cleaning fluid is 1.5940 g/mL. Draw a mass-balance diagram and estimate the monthly % of mass residue to be dosposed of.A 98% efficient ESP follows the Deutsch equation. If the gm flow rate changes and the efficiency drops to 94%, calculate the ratio of the new gas flow rate to the old gas flow rate,Problem 2Approximately 30 kg of consumer products are brought into a home by its residents on a weekly basis. Two thirdsof this quantity are used as food, and about 2 kg of these products remain in the house. Every week, 75% of thewaste is collected at the curb, with the remainder sent to recycling.1. Plot the mass balance diagram of the house showing the mass of inputs, accumulations and outputs.2. Estimate how much solid waste the residents leave out to the curb each week.
- Water is available at a rate of 2000 L/min to a small apartment complex, consisting of four units.
