Along, uninsulated steam line with a diameter of 100 mm and a surface emissivity of 0.8 transports steam at 150°c and is exposed to atmospheric air and large surroundings at an equivalent temperature of 20°c. (a) calculate the rate of heat loss per unit length for a calm day. (b) calculate the rate of heat loss on a breezy day when the wind speed is 8 m/s. (c) for the conditions of part (a), calculate the rate of heat loss with a 20-mm-thick layer of insulation (k = 0.08 w/m ⋅ k). would the heat loss change significantly with an appreciable wind speed?

that would be b i just took the test : )

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

the answer is 3.1 his answer is wrong mines is right

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
