It is required to layout on the ground a rectangular lot 505.20 m long and 251.70 m wide. The tape to be used is exactly 100 m at 10 kg pull at 28 degrees celcius temperature. If the actual fieldword will be done at temperature 50 degrees celcius and the applied pull is 10 kg, what is the corrected area if the coefficient of thermal expansion for the tape is 0.0000116 per degrees celcius.

1. Water 3m/s 75mm Þ Determine mass flow rate [13.26 kg/s] 2. Oil RD = 0.86 +17 kg/s 100mm Þ Determine velocity [2.52 m/s] Given viscosities of water and oil are 0.001 Ns/m² and 0.03 Ns/m² respectively, determine the Reynolds number in examples 1. and 2. [2.25 X 10°, 7224] 3.

The average weather conditions for a place are as follows: net radiation = 40 W/m²; air temperature = 28.5°C; relative humidity = 55%; and wind speed = 2.7 m/s at a height of 2 m. Calculate the open water evaporation rate in mm per day using the energy method, aerodynamic method, combination method, and the Priestley-Taylor method. Assume standard atmospheric pressure is 101 kPa and zo is 0.03 cm.

Use Darcy's law to calculate the equivalent hydraulic conductivity in cm/second. Water flow is as indicated for each of the 3 layers. N- 91.44 cm -X LAYER 182.88 cm LAYER 2 LAYER || | || 60.96 cm GRADE LAYER 1 2 3 Kx (cm/sec) 0.0106680 0.0000686 0.0014478 Kz (cm/sec) 0.0261620 0.0002134 0.0086360
