Storage at end of March = Storage at beginning of January + Cumulative inflows - Cumulative outflows
=60+(4+6+9)-(8+11+5)
=60+19-24
=55 m3
1. A reservoir has the following inflows and outflows (in cubic meters) for the first three...
A shallow reservoir has a one-square-kilometer water surface and an average water depth of 4 meters. Initially it is filled with fresh water, but at time t 0 water contaminated with a liquid pollutant begins flowing into the reservoir at the rate of 500 thousand cubic meters per month. The well-mixed water in the 60 80- reservoir flows out at the same rate. Your first task is to find the amount x(t) of 40- pollutant (in millions of liters) in...
3. Compute a weekly evaporation rate (in mm/week) from the surface water reservoir applying the following recorded data: average inflow into water reservoir = 32.5 m3/s, average outflow from reservoir = 40.2 m3/s, average rainfall during the week = 73.6 mm, surface water reservoir area = 15.8 km², estimated total water infiltration or seepage out during the week from this reservoir = 0.25 million m”, reservoir storage at the beginning of week = 9180 ha-m (hectare-meter), reservoir storage at the...
A shallow reservoir has a one-square-kilometer water surface and an average (+ water depth of 4 meters. Initially it is filled with fresh water, but at time t 0 water 80 contaminated with a liquid pollutant begins flowing into the reservoir at the rate of 200 thousand cubic meters per month. The well-mixed water in the reservoir 60- flows out at the same rate. Your first task is to find the amount x(t) of pollutant (in 40- millions of liters)...
1. A fund had $60 million under management at the beginning of January. The fund's return for January was -1.9% and the fund received $4.3 million new capital inflow at the month end. What was the fund's portfolio value at this point? 2. Continued with Q1. Suppose the fund earned 5.6% return but experienced $5.3 million capital outflow for February. What was its portfolio value at the end of Feb. ? 3. Continued with Q1 and Q2. For March the...
Determine the total cash inflows, the total cash outflows, and the expected change in cash for each month from January to July, 2019. Show your work in excel using excel functions. Based the findings, explain in your own words whether the company should borrow/invest and how much and in which months. The management estimates total sales for the period January, 2019 through June 2019 based on actual sales from the immediate past six months. The following assumptions are made: The...
Question Help 1.5.45 A shallow reservoir has a one-square-kilometer water surface and an average water depth of 4 meters. Initially it is filled with fresh water, but at timet=0 water contaminated with a liquid pollutant begins flowing into the reservoir at the rate of 500 thousand cubic meters per month. The well-mixed water in the reservoir flows out at the same rate. Your first task is to find the amount x(t) of pollutant (in 40- millions of liters) in the...

Problem 2 A rectangular 3-acre lot is being developed into multifamily housing. Can this plot of land be considered a watershed? Why or why not? Problem 3 Three centimeters of water evaporated from a 200-hectare vertical walled reservoir during 24 hours. Storm water was added to the reservoir at a constant rate of 3 ms during this period. Determine the volume in ha-cm of water released during the period (through the bottom of the reservoir) if the water level in...
1. A water supply reservoir has been lined with clay to limit leakage (infiltration through the bottom An assessment of the effectiveness of the liner is required to fulfill the terms of the construction contract. The following data have been collected for a test week: Day Parameter Stream inflow (m/sec ) Stream outflow (m/sec) City use (m/sec) Precipitation (cm) 1 0.0 0.0 0.3 0.0 2 0.2 0.1 0.2 1.5 3 0.4 0.3 0.3 2.0 4 0.5 0.2 0.2 2.5 5...
Q3: A small retailer has studied the weekly cash flows past data and developed the following information Inflow (S) probability probability Outflow (S) 0.3 5000 0.2 4000 0.4 6000 0.3 5000 0.2 8000 0.4 7000 Using the random numbers for a period of 6 weeks given below: 38 73 55 17 46 Outflows: 68 6 30 72 46 88 Inflows: 9 a) Simulate the weekly pattern of Outflows and Inflows for the next 6 weeks to devise better cash management...
