Answer:

Explanation:

1). Average speed of a skydiver = \frac{\text{Distance covered}}{\text{Time taken}}

                                                    = \frac{9}{2.5}

                                                    = 3.6 km per minute

2). Average speed of the butterfly = \frac{30}{14}

                                                         = \frac{15}{7}

                                                         = 2\frac{1}{7} meter per second

3).  Average speed of the race car = \frac{500}{3}

                                                          = 166\frac{2}{3} miles per hour

4).Average speed = \frac{\text{Distance traveled}}{\text{Time taken}}

 Distance traveled = Average speed × Time

                                = 85 (km per hour) × 3.5 (hours)

                                = 297.5 km

During typical urination, a man releases about 400 mL of urine in about 30 seconds through the urethra, which we can model as a
gregori [183]

Answer:

Explanation:

Given:

volume of urine discharged, V=400~mL=0.4~L=4\times 10^{-4}~m^3

time taken for the discharge, t=30~s

diameter of cylindrical urethra, d=4\times10^{-3}~m

length of cylindrical urethra, l=0.2~m

density of urine, \rho=1000~kg/m^3

a)

we have volume flow rate Q:

Q=A.v & Q=\frac{V}{t}

where:

A= cross-sectional area of urethra

v= velocity of flow

A.v=\frac{V}{t}

\frac{\pi d^2}{4}\times v=\frac{4\times 10^{-4}}{30}

v=\frac{4\times4\times 10^{-4}}{30\times \pi (4\times 10^{-3})^2}

v=1.06~m/s

b)

The pressure required when the fluid is released at the same height as the bladder and that the fluid is at rest in the bladder:

P=\rho.g.l

P=1000\times 9.8\times 0.2

P=1960~Pa
