Sammy’s seashore supplies rents beach equipment such as kayaks, canoes, beach chairs, and umbrellas to tourists. in chapters 3 and 4 you created a rental class for the company.

now, make the following change to the class:

currently, a rental price is calculated as $40 per hour plus $1 for each minute over a full hour. this means that a customer who rents equipment for 41 or more minutes past an hour pays more than a customer who waits until the next hour to return the equipment. change the price calculation so that a customer pays $40 for each full hour and $1 for each extra minute up to and including 40 minutes.

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.
