A treatment plant is planned to be installed in a recreational resort that contains a developed campground for 200 persons, lodges and cabins for 100 persons, and resort apartments for 150 persons. Assume that persons staying in lodges use the dining hall for 3 meals/day and that a 50 seat cafeteria with 4 employees and an estimated 200 customers/day has been constructed. Daily attendance at the visitor center is 500 persons. Other facilities include a 10-machine laundromat, a 20 seat cocktail lounge, and three gas stations (1100 L/d per station). Determine the average wastewater flowrate in L/d using the unit flows assuming the housing facilities are at maximum capacity.

2. At the beginning of 2006, the rate of energy consumption for the city of Denver was 7000 megawatts (MW), where 1 MW = 106 W. The rate was expected to increase at an annual growth rate of 2% per year. a) Find the function that gives the rate of energy consumption for all times after the beginning of 2006. b) Find the total amount of energy used during the year 2010. Note: the entire year 2010 corresponds to the interval 4 < t < 5.
The average electricity consumption of a house in Gainesville is known to be 1,036 kWh in a month (One month = 30 days). They would like to install solar panels of 30 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m² but do not write the unit. Round off you E swer to a whole number (zero decimal place.)
In a home, 8 lamps, 3 fans and 2 Air conditioners are used. The ratings of each lamp is 40 Watts. The ratings of each fan is 75 Watts. The ratings of each Air conditioners is 1300 Watts. Calculate the total electrical energy consumed by these loads for last month (February 2021).
The average electricity consumption of a house in Gainesville is known to be 924 kWh in a month (One month = 30 days). They would like to install solar panels of 24 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m² but do not write the unit. Round off you answer to a whole number (zero decimal place.)
Solar energy stored in large bodies of water, called solar ponds, is being used to generate electricity. If such a solar power plant has an efficiency of 3 percent and a net power output of 180 kW, determine the average value of the required solar energy collection rate, in Btu/h.
(a) Considering the numbers of heads and tails, how many macrostates are there when five coins are tossed? (b) What is the total number of possible microstates in tossing five coins? (c) Find the number of microstates for each macrostate and be sure that the total agrees with your answer to part (b).
Question-3: As advertisement revenue, billboards on vehicles can be used frequently. However, this fuel increases the cost. A block of 0.3m high, 0.9m wide and 0.9m long was placed on a taxi. Find the annual increase in fuel cost due to this billboard. Assume that the vehicle travels 60000 km per year, an average speed of 50 km / h and a total engine efficiency of 28%. Take the density, unit price and calorific value of gasoline as 0.75kg / L 5.5TL / L and 42000kJ / kg, respectively, and the density of the air as 1.25 kg / m3.
In Arizona, photovoltaic (PV) panels can generate an average annual power of 1 MW/acre. If there are 311 sunny days per year in Arizona, but only 160 sunny days per year in Pennsylvania, how much average power (in MW/acre) could the same PV panels generate in Pennsylvania? Please include two decimal places in your answer. Note: assume that a cloudy day delivers 0 watts/acre of solar power. This is not true, but it simplifies the problem for us.
Problem 2) An electric lawn mower runs on 1000 watts of electrical power input. The same mower can cover a small yard of 2500 sq ft in 20 minutes (20 minutes is 1200 seconds). If the effective amount of energy required to cut the 2500 sq ft of grass is 420,000 joules. What is the efficiency of the electric lawnmower? Problem 3) The small wheel in the picture has a radius of 1 inch and the large one has a radius of 8 inches. The yarn that connects them travels at a speed of 12 inches/second. If the small wheel rotates at 800 RPM, what is the rotational speed of the large wheel? Radius : 8 inches Radius : 1 inch

For most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case.
The solar panels are placed in an optimal position such that they receive a solar power of 1186kWh/m^2 per year1. The average solar cell has an efficiency of 20% and an average household in the Netherlands uses 2990kWh of electricity per year. The average solar panel has dimensions of 165x99cm. How many solar panels do you need?
