- Fluid runs through a drainage pipe with a 10-cm radius and a length of 30m (3000 cm). The velocity of the fluid gradually decreases from the center of the pipe toward the edges as a result of friction with the walls of the pipe. For the data shown, v(x) is the velocity of the fluid (in. cm/sec) and x represents the distance (in. cm) from the center of the pipe toward the edge. x 0 1 2 3 4 5 6 7 8 9 v(x) 195.5 195.1 194.5 193.5 192.2 190.6 188.8 186.6 184.2 181.5 Use regression to find a quadratic function to model the data.

Use the data to determine the constants a and b that best fit the data.arrow_forwardConsider a water tank that is being filled with rainfall at the top and is drained through a small hole at the bottom. The change in volume can be modelled by considering the amount of water entering and leaving the tank (per unit of time) as follows dV dt fin - fout. Here volume of water in the tank V is in litres, flow rate in fin is in litres per hour, flow rate out fout is. in litres per hour and time t is in hours. Initially, the tank contains 50L of water: V(0) = 50. (a) Assume the rainfall throughout the day is getting heavier, such that, fin(t) = 10 + t and that the tank is losing 10% of its volume of water per hour, such that, fout (V) = 0.1V. Check by direct substitution that the function V(t) = 10(t + 5e-0.1t) satisfies the ODE and the initial condition. (b) Now assume that the hole is slowly growing in size, so that the flow rate out increases with time: fout (V, t) = 0.1(1 + 0.1t) V. Solve the ordinary differential equation for V(t) with this flow rate out, using either…arrow_forward

- Mist (airborne droplets or aerosols) is generated when metal-removing fluids are used in machining operations to cool and lubricate the tool and workpiece. Mist generation is a concern to OSHA, which has recently lowered substantially the workplace standard. An article gave the accompanying data on x = fluid-flow velocity for a 5% soluble oil (cm/sec) and y the extent of mist droplets having diameters smaller than 10 µm (mg/m³): 85 177 190 354 360 442 960 0.39 0.60 0.45 0.66 0.60 0.69 0.90 (a) The investigators performed a simple linear regression analysis to relate the two variables. Does a scatter plot of the data support this strategy? Yes, a scatter plot shows a reasonable linear relationship. No, a scatter plot does not show a reasonable linear relationship. (b) What proportion of observed variation in mist can be attributed to the simple linear regression relationship between velocity and mist? (Round your answer to three decimal places.)

The rate, in dollars per second, that money is coming out of the ATM is modeled by the function M'(t), where t is measured in seconds.
