Textbook Question
Chapter 16.4, Problem 11CC
The height of water slowly draining from a large barrel follows an exponential model: h = h0 emt. The following three measurements of Height (h) [ft] versus time (t)
[min] were recorded:
t = 4, h = 6.7; t = 7, h = 5.6; t = 15, h = 3.8
If a pump turns on to refill the barrel when the height drops below one foot, when (min) will the pump turn on? All calculation must be done in MAT LAB, not by hand.

The amount of time it takes for a pendulum to swing “to-and-fro” through one complete cycle is called the “period” and is calculated using the following equation:
where
T = period in seconds, I = mass moment of inertia, m = mass of pendulum in kilograms
g = gravitational acceleration, 9.8 m/s2, h = effective length of pendulum in meters
What is the appropriate unit for I if the preceding equation is to be homogeneous in units? Please show all of your work.

Question : A 550 kilogram mass initially at rest acted upon by a force of F(t) = 50et Newtons. What are the acceleration, speed, and displacement of the mass at t = 4 second ?
a =(50 e^t)/(550 ) [N/kg]
v = ∫_0^t▒(50 e^t )dt/(550 )= v_0 +(50 e^t-50)/550=((e^t- 1))/11
x = ∫_0^t▒(e^t- 1)dt/(11 )= x_0 +(e^t- t - 1)/(11 )
a(4s)=(50*54.6)/550= 4.96[m/s^2 ]
v(4s)=((e^4-1))/11= 4.87[m/s]
x(4s)=((e^4- 4 - 1))/11= 4.51 [m]

- The Reynolds number is a dimensionless group defined as follows for a liquid that flows through a pipe: Re = Dvρ / μ where D is the diameter of the pipe, v is the velocity of the fluid, ρ is its density and µ its viscosity. When the Reynolds number value is less than 2100, the flow is laminar, that is, the liquid it moves in lines of smooth flow. For Reynolds numbers greater than 2100, the flow is turbulent, characterized by considerable agitation. Liquid Methyl Ethyl Ketone (MEK) flows through 2067 '' ID tubing and through an average velocity of 0.48 ft / s. If the fluid temperature is 20 ° C, the density of the MEK The liquid is 0.805 g / cm and the viscosity is 0.43 cP (1 cP = 1.00 x 10 kg / (m-s)].
