$3\mathrm{.}1\mathrm{.}27.[$Level $2]$ A flatbed truck is traveling at a speed

$v_1$ in the i direction and is brought to a stop with a constant

deceleration over a distance $D.$ What is the minimum value

E$3\mathrm{.}1\mathrm{.}27$

In pan measurements close to a reservoir, the following data were observed on a certain day.

Determine the daily evaporation by $($a$)$ the simple formula assuming that $K=0\mathrm{.}7,$ and $($b$)$ the

revised formula, assuming that $K^{\text{'}}=1\mathrm{.}5$ at $4$ m $.$

Pan evaporation $=15mm$

Mean air temperature $at4m=23C$

Maximum reservoir temperature $=18C$

Minimum reservoir temperature $=15C$

Maximum pan temperature $=24C$

Minimum pan temperature $=18C$

Relative humidity $=47\%$

Use the Aerodynamic Method to estimate the evaporation for Problem #$3$ if the wind speed is $23$

$\frac{m}{s}$ and $C_E=1\mathrm{.}3{10}^{-3}$ at $4$ m $.$ You may assume the mean reservoir temperature is the average of

the maximum and minimum temperatures and that the atmospheric pressure is $101\mathrm{.}1$ kPa $.$
