Anuclear fuel element of thickness 2l is covered with a steel cladding of thickness b. heat generated within the nuclear fuel at a rate q . is removed by a fluid at t, which adjoins one surface and is characterized by a convection coefficient h. the other surface is well insulated, and the fuel and steel have thermal conductivities of kƒ and ks, respectively. (a) obtain an equation for the temperature distribution t(x) in the nuclear fuel. express your results in terms of q . , kƒ, l, b, ks, h, and t. (b) sketch the temperature distribution t(x) for the entire system

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
