In a single-flash geothermal power plant, geothermal water enters the flash chamber (a throttling valve) at 230C as a saturated liquid at a rate of 50 kg/s. The steam resulting from the flashing process enters a turbine and leaves at 20 kPa with a moisture content of 5 percent. Determine the temperature of the steamafter the flashing process and the power output from the turbine if the pressure of the steam at the exit of the flash chamber (2) is 1 MPa

Suppose we have four jobs in a computer system, in the order JOB1, JOB2, JOB3 and JOB4. JOB1 requires 8 s of CPU time and 8 s of I/O time; JOB2 requires 4 s of CPU time and 14 s of disk time; JOB3 requires 6 s of CPU time; and, JOB4 requires 4 s of CPU time and 16 s of printer time. Define the following quantities for system utilization: Turnaround time = actual time to complete a job Throughput = average number of jobs completed per time period T Processor utilization = percentage of time that the processor is active (not waiting) Compute these quantities (with illustrations if needed) in each of the following systems: a. A uniprogramming system, whereby each job executes to completion before the next job can start its execution. b. A multiprogramming system that follows a simple round-robin scheduling. Each process gets 2 s of CPU time turn-wise in a circular manner.

engineers are designing a system by which a falling mass imparts kinetic energy to a rotating uniform drum to which it is attached by thin, very light wire wrapped around the rim of the drum (fig. p9.64). there is no appreciable friction in the axle of the drum, and everything starts from rest. this system is being tested on earth, but it is to be used on mars, where the acceleration due to gravity is in the earth tests, when is set to 15.0 kg and allowed to fall through 5.00 m, it gives 250.0 j of kinetic energy to the drum. (a) if the system is operated on mars, through what distance would the 15.0 kg mass have to fall to give the same amount of kinetic energy to the drum? (b) how fast would the 15.0 kg mass be moving on mars just as the drum gained 250.0 j of kinetic energy?
