The typical soda can is 2.5 inches in diameter and 4.5 inches high. You would think that the cans would be designed such that the total surface area is minimized, thus minimizing total material costs. However, the size of a soda can (2.5 inches in diameter and 4.5 inches high) is NOT the optimum size that minimizes total surface area. a. Using Matlab, solve for the size of a can that would minimum total surface area that has the same volume as the typical soda can (2.5 inches in diameter and 4.5 inches high). b. Based upon your result from part a, why do you think soda cans are designed the way that they are

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)
