Q8): To find how much heat is required to bring a kettle of water to its boiling point, you are asked to calculate the specific heat of water at 61°C. The specific heat of water is given as a function of time in Table below. Temperature, T Specific heat, C₂ (°C) J kg-°C 22 42 52 82 100 4181 4179 4186 4199 4217 Determine the value of the specific heat at 7=61°C using the direct T method of interpolation and a third order polynomial. Find the absolute relative approximate error for the third order polynomial approximation (Lagrange Method).
For all the following problems, a) b) 4. You need to show at least 3 iterations calculated manually with all steps. You do not need to include the M.files for the bisection method (bisect.m) and for false position (falspos.m). You must, however, show the command lines for the given functions with their variables and other parameters. Zero-pressure specific heat of dry air Mechanical engineers, as well as most other engineers, use thermodynamics extensively in their work. The following polynomial can be used to relate the zero-pressure specific heat of dry air cp kJ/(kg K) to temperature (K): 11 0.99403 +1.671×10-4T + 9.7215-10-8T²-9.5838×10- Cp = T3+1.9520×10-14T4 (a) Develop a plot of cp versus a range of T=0 to 1200 K. (b) Use bisection to determine the temperature T that corresponds to a specific heat of 1.1 kJ/(kg K). (c) What will be the value of T if you use false position method? (d) What is the percentage error between the results of (b) and (c)? For both methods use maximum…
In a study analyzed by the Statistics Consulting Center at Mutah University, a group of subjects was asked to complete a certain task on the computer. The response measured was the time to completion. The purpose of the experiment was to test a set of facilitation tools developed by the Department of Computer Science at the university. There were 10 subjects involved. With a random assignment, five were given a standard procedure using Fortran language for completion of the task. The other five were asked to do the task with the use of the facilitation tools. The data on the completion times for the task are given here. Group 1 Group 2 (Standard Procedure) (Facilitation Tool) 161 169 174 158 163 132 162 134 138 133 Assuming that the population distributions are normal and variances are the same for the two groups, support or refute the conjecture that the facilitation tools increase the speed with which the task can be accomplished.

Fanning friction factor For fluid flow in pipes, friction is described by a dimensionless number, the Fanning friction factor f. The Fanning friction factor is dependent on a number of parameters related to the size of the pipe and the fluid, which can all be represented by another dimensionless quantity, the Reynolds number Re. A formula that predicts ƒ given Re is the von Karman equation: 4log₁0 (Re√) - 0.4 = Typical values for the Reynolds number for turbulent flow are 10,000 to 500,000 and for the Fanning friction factor are 0.001 to 0.01. (a) Develop a function that uses bisection to solve for fgiven a user-supplied value of Re between 500 and…
