G Two streams of humid air are to be mixed to produce 600 cfm of air at 30°C and 30% relative humidity. If stream 1 is 200 cfm at 20°C and saturated, what is (a) the mass flow rate of stream 2, (b) the temperature (dry bulb) of stream 2, and (c) the relative humidity of stream 2? (25 points) Show the process on a psychrometric chart (5 points).

false

explanation:

boats, things on boats luggage are way more heavy then water.

unbalanced force

explanation:

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
