MO22. Supercavitation is a propulsion technology for undersea vehicles that can greatly increase their speed. It occurs aboveapproximately 50 meters per second, when the pressure drops off sufficiently to allow the water to dissociate into water vaporforming a gas bubble behind the vehicle. When the gas bubble completely encloses the vehicle, supercavitation is said to occur.Eight (n = 8) tests were conducted on a scale model of an undersea vehicle in a towing basin with the average observed speed x =102.2 meters per second. Assume that speed is normally distributed with o = 4 meters per second. Use a = 0.05, test Ho: H = 100versus H1 : µ < 100. What is the value of zo (2 decimal places, 0.00) and what can be concluded?

Consider the mixing process shown in the figure. A mixing chamber initially contains 4 liters of a clear liquid. Clear liquid flows into the chamber at a rate of 10 liters per minute. A dye solution having a concentration of 0.6 kilograms per liter is injected into the mixing chamber at a constant rate of r liters per minute. When the mixing process is started, the well-stirred mixture is pumped from the chamber at a rate of 10 + r liters per minute. (a) Develop a mathematical model for the mixing process. Let Q represent the amount of dye in kilograms in the mixture. dQ kg/min dt (b) The objective is to obtain a dye concentration in the outflow mixture of 0.5 kilograms per liter. What injection rate r is required to achieve this equilibrium solution? 7 = L/min Would this equilibrium value of r be different if the fluid in the chamber at time t = 0 contained some dye? no (c) Assume the mixing chamber contains 4 liters of clear liquid at time t = 0. How many minutes will it take for the…

The growth of malignant tumors can be modeled using the Gompertz model. dP dt r.P. where r>0 is the intrinsic growth rate and K> 0 is a constant. a) Find the general solution to the Gompertz model and state the significance of the constant K. b) A tumor with 2,500 cells is initially growing at a rate of 500 cells/day. Assuming the maximum size of the tumor is 100,000 cel how large will the tumor be after 50 days?
A tank contains 200 liters of fluid in which 30 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pumped into the tank at a rate of 4 L/min; the well-mixed solution is pumped out at the same rate. a) Find the number A(t) of grams of salt in the tank at time t. b) Repeat part a, assuming that pure water is pumped into the tank. 200 L
A student is concerned with the amount of air pollution students are exposed to in the school's parking lot after school. The student conducts an investigation to compare the quantity of particulate matter released from the diesel-powered buses, natural gas-powered buses, and the large and small cars as they idle waiting to pick up students. To make measurements, a small piece of white fabric is used to collect particulate matter from the tailpipe of each vehicle as it idles for five minutes. Each piece of fabric is then analyzed to measure the amount of particulate matter it collected. (i) Identify the independent variable in the investigation. (j) Identify one variable that was not mentioned in the description that could affect the results of the investigation. (k) Describe a realistic alternate sampling method to collect particulate matter from the vehicles in the investigation. (1) The student wants to ensure that the results are reliable. Explain how the student could modify the…
Supercavitation is a propulsion technology for undersea vehicles that can greatly increase their speed. It occurs above approximately 50 meters per second, when the pressure drops off sufficiently to allow the water to dissociate into water vapor forming a gas bubble behind the vehicle. When the gas bubble completely encloses the vehicle, supercavitation is said to occur. Eight (n = 8) tests were conducted on a scale model of an undersea vehicle in a towing basin with the average observed speed I = 102.2 meters per second. Assume that speed is normally distributed with o = 4 meters per second. Use a = 0.05. (a) Test Ho:µ = 100 versus H1:µ < 100. (b) Compute the power of this test if the true mean speed is low as 95 meters per second. Round your answer to four decimal places (e.g. 98.7654). (c) What sample size would be required if we want to detect a true mean speed as low as 94 meters per second if we wanted the power of the test to be at least 0.85.
Tank B, a 30-litre tank, initially contains 6 grams of salt in 15 litres of water. At t = 0, saltwater with a concentration of 1 gram of salt per litre is poured from Tank A into Tank B at a rate of 2 litres per minute, while the well mixed solution leaves the bottom of Tank B at a rate of one litre per minute. a) derive the IVP that models the rate of change of the quantity of salt in Tank B with respect to time,b) solve the IVP, andc) determine the quantity and concentration of salt in Tank B at the instant Tank B is full
Water is leaking out of an inverted conical tank at a rate of 11500.000 cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height 9.000 meters and the diameter at the top is 4.500 meters. If the water level is rising at a rate of 21.000 centimeters per minute when the height of the water is 2.000 meters, find the rate at which water is being pumped into the tank in cubic centimeters per minute.
