1) Aris uses a boat to cross from one side to the other side of a river of width w = 32 m. The river flows at VC = 8 m/min. and he can row at a speed of VB =30 m/min. in still water. He wants to land at a dock which is L=10 m downstream from a point directly opposite his starting point. a) In what direction (i.e. angle relative to the bank), should he aim his boat upstream? b) How long will it take for him to make this crossing?

2) The speed of an aircraft in still air (air speed) is 600 km/h. The wind velocity is 120 km/h blowing from the east. The aircraft is steered in the direction [E 30° S] that is a bearing of 120°. Find the ground velocity vector of the aircraft. (Draw an appropriate vector diagram.)

3) An airplane whose airspeed is 610 km / h is supposed to fly in a straight path 35.0 o North of East. But a steady 85 km / h wind is blowing from the North. In what direction should the plane head?

1. Two reactors, one of them a CMBR and the other a CSTR, are operating side by side in parallel. Each is treating one half of a total flow rate of 800 gal/min containing a substance that enters at a concentration of 80 mg/L and experiences first-order degradation with a k value of 0.1/min. The reactors have identical volumes of 8000 gal, so they also have equal liquid retention times of 20 min. (a) What is the concentration of the...

One end of the straw is blocked by a finger when You pushed the other side of straw under water h_0 (m) and right after that finger is removed from end of straw. You can see the level of water in the straw is rising. Find the depth of water in the straw h(t). Consider the situation as quasi equillibrium state and neglect the surface tension.

Q2) A trapezoidal wadi 3 m wide and 2:1 side slope is to cross a road at station 1+120. The drainage area is 50-hectare consisting of bare earth with steep slopes. A concrete box culvert is considered to drain the wadi assuming 15 minutes concentration-time and a 20-years return period. Determine the minimum width of the culvert to the nearest 10 cm assuming one meter maximum culvert depth, two meter allowable headwater depth, 1% culvert slope (same as the Wadi...

Suppose that we cross two flies: One is a female that is b+b vg+vg; the other is a male that is homozygous recessive. The female has grey (wild-type) body and normal (wild-type) wing length. The male is black-bodied with vestigial wings. The female's parents (I'm going to refer to them as the grandparents) were a true-breeding grey, normal fly and a true-breeding black, vestigial fly.

Tina can row a boat at 2.60 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.90 mi/h. Not having her calculator she guesses that to go straight across she should head upstream at an angle of 25.0° from the direction straight across the river. a. How long does it take her to cross the river? b. What is her speed with respect to the starting point on the...
