Life Expectancy of a Female Suppose that in a certain country the life expectancy at birth of a female is changing at the rate of $g(t) = \frac{3.80668}{(1 + 1.02t)^{0.9}}$ years/year. Here, $t$ is measured in years, with $t = 0$ corresponding to the beginning of 1900. Find an expression $q(t)$ giving the life expectancy at birth (in years) of a female in that country if the life expectancy at the beginning of 1900 is 37.34 years. $q(t) = $ What is the life expectancy (in years) at birth of a female born in 2000 in that country? (Round your answer to two decimal places.)

500 kg h?¹ of steam drives a turbine. The steam enters the turbine at 40 bar and 450°C at a linear velocity of 60 m s?¹ and leaves at a point located 5 m below the turbine inlet at 1 bar and velocity of 360 m s?¹. The turbine delivers shaft work at a rate of 70 kW, and the heat loss from the turbine is estimated to be 41.84 \times 10³ kj h?¹. Calculate: a. Change of rate of potential energy (in kW) associated with the process; b. Change of rate of kinetic energy (in kW) associated with the process; c. Change of rate of enthalpy (in kW) associated with the process; d. Change of specific enthalpy (kj kg?¹) associated with the process.
