An airplane is flying in a horizontal circle at a speed of 100 m/s. The 80.0 kg pilot does not want the centripetal acceleration

Tema [17]

Answer:

The force will be "5,488". A further solution is provided below.

Explanation:

The given values are:

speed,

v = 100m/s

mass,

m = 80 kg

acceleration,

a = 7

Now,

Radius will be:

⇒ $r=\frac{v^2}{ac}$

⇒ $=\frac{(100)^2}{7\times 9.8}$

⇒ $=\frac{10000}{68.6}$

⇒ $=145.77$

Force will be:

⇒ $F=m\times ac$

⇒ $=80\times 68.6$

⇒ $=5488$

A 3 inch fire hose has a water flow of 200 gallons per minute. What is the flow in liters per second? Note: Use US gallons not U

stepladder [879]

Answer:

Case I: 12.617 L/s

Case II: 161.406 cubic meters per hour

Case III: 1.062 Pound inches

Explanation:

Given:

Speed of water flow = 200 gallons per minute
Speed of air blow = 95 cubic feet per minute
Measure of Torque = 12 Newton centimeter

Assumptions:

1 US gallon = 3.785 L
1 min = 60 s
1 ft = 0.3048 m
1 h = 60 min
1 inch = 2.54 cm
1 N = 0.2248 lb

Case I:

$Speed\ of\ water\ flow = 200 \dfrac{gallon}{min}\\\Rightarrow V_{water} = 200\times \dfrac{3.785\ L}{60\ s}\\\Rightarrow V_{water} = 12.617\ L/s$

Case II:

$Speed\ of\ air\ blow = 95 \dfrac{ft^3}{min}\\\Rightarrow V_{air} = 95\times \dfrac{(0.3048\ m)^3}{\dfrac{1}{60}\ h}\\\Rightarrow V_{air} = 95\times (0.3048)^3\times 60\ m^3/h\\\Rightarrow V_{air} = 161.406\ m^3/h$

Case III:

$Measure\ of\ torque = 12\ N cm\\\Rightarrow \tau = 12\times (0.2248\ lb)\times \dfrac{1}{2.54}\ in\\ \Rightarrow \tau = 1.062\ lb in$
