Problem #3 (Evaporation): Evaporation from a lake can be obtained from the Penman equation. If the available energy at the lake surface is 200 W m, aerodynamic resistance is 30 s m', and air specific humidity is 10 g kg', what is the change in evaporation (in mm day") if the air temperature is reduced from 20°C to 15°C as a cold air mass passes over the lake?

WATER RESOURCES ENGINEERING: Measurements of a water-balance have been made for a one-year period on a lake with an area of 0.8 km2 with the following results: P = 1400 mm, Qsi = 0.15 m3s-1 and Qso = 0.17m3s-1. The lake surface elevation, h, at the end of the year was 45mm lower than at the beginning. What is the estimate (in mm) of the lake evaporation for that year?
A lake with a surface area of 275 ha has the values of: relative humidity = 60% wind velocity at 1m above the ground = 10 kph mean barometric reading 750 mmHg es = 30 mmHg Km = 0.36 Estimate the average daily evaporation from the reservoir and the volume of water evaporated in the body in 5 days using MEYERS
For an irrigation project for an area of 10.000 km2 water has to be transported to compensate for natural evaporation. The total evaporation per year is the equivalent to a yearly rainfall of 30 cm. The water flows through an open channel of 100 km length from a lake 100 m higher than the irrigation area. The transport channel is 3 m deep but the water level is just 2 m. The channel has a rectangular shape and a friction factor of 4.10-3. Make an estimate about how wide the channel should be assuming steady-state conditions. The width of the channel is significantly larger compared to the water level height in the channel.
The monthly pan evaporation measured in a lake for the month of January was 16.7 cm. If the average water surface area is 2.55 sq.km, estimate the evaporation loss that month in cubic meters if the pan coefficient is 0.70?
Estimate the outflow from a 2500 hectare lake in 20 days during which the lake level dropped by 105cm, an average inflow into the lake 5x10^5 m^3/day.During 20 days, the seepage loss from the lake was 5.5cm,total precipitation on the lake was 0.25m while the total evaporation was 15mm. Give final answer in m^3/s.
Problem 1: Water BalanceMeasurements of water-balance components have been made for a one-year period on a lake with an area of 0.8 km2 with the following results: P = 1400 mm, Qsi = 0.15 m3 s-1, and Qso = 0.17 m3 s-1. The lake-surface elevation, h, at the end of the year was 45 mm lower than at the beginning. What is the estimate (in mm) of the lake evaporation for that year?
A total of 10 mm of rainfall fell on a lake with a surface area of T km^2 in June 1996.

A lake has a surface area of 7.0 x 105 m² During a given month, the mean inflow to the lake was 2.5 m³/s. The increase in stored lake volume was observed to be 6.5 x 10 m². Precipitation during the same month was 380 mm and evaporation was 320 mm. Calculate the outflow from the lake for the same month in m/s.
A lake with a surface area of 275 ha has the values of: relative humidity = 60% wind velocity at 1m above the ground = 10 kph mean barometric reading = 750 mmHg es = 30 mmHg Km = 0.36 Estimate the average daily evaporation from the reservoir and the volume of water evaporated in the body in 5 days using ROHWERS
A small shallow reservoir has a surface area of 150 square meters is used to estimate the average daily evaporation. The average values of climate parameters during a week are the following: water temperature is 34 degrees Celsuis, relative humidity of 0.3, wind velocity at 1.0 meter above ground surface is 4.444 m/s. Use the Meyer's formula to get the average daily evaporation. Also, compute the total volume of water lost due to evaporation daily.
Estimate monthly evaporation for a large lake for the month of July using the Meyer Equation for the folowing data: - Mean montly air temperature: 70F - Mean montly relative humidity: 60% - Mean monthly wind speed at 25 ft height: 30 mile/hr Also compute for the amount of evaporation expected from a lake per week for the data as: -Lake water temperature: 78F - Air temperature: 90F - Wind mileage - 1680 miles/week at 25 ft
