Problem 16E

According to Newton's law of cooling, the time needed for an object at an initial temperature to cool to a temperature in an environment with ambient temperature is given by where is a constant. Assume that for a certain type of container, . Let be the number of minutes needed to cool the container to a temperature of . Assume that and . Estimate , and find the uncertainty in the estimate.

Step-by-Step Solution:

Step 1 of 2

In this question we are asked to find the estimate of Newton’s law cooling equation and the uncertainty in the estimate.

Newton’s law cooling equation = - …………..(1)

Where

t is the number of minutes needed to cool the container is a initial temperature is an ambient temperature is a constant is a cooling temperature

Given parameters: = 0.025 , = 70.1 ± 0.2°F, = 35.7 ± 0.1 °F and The quantity which we are estimating has several measurements. In this question we are measuring the initial temperature and ambient temperature . These quantity mentioned here is uncertain and independent measurements.

So here we can use the following basic formula. ……………...(2)

Where , ,........, are independent measurements and uncertainties are , ,........., Equation 2 is called the multivariate propagation of error formula.

Step 2 of 2
