"Vehicles begin to arrive at a parking lot at 6:00 A.M. at a rate of eight per minute. Due to an accident on the access highway,
no vehicles arrive from 6:20 to 6:30 A.M. From 6:30 A.M. on, vehicles arrive at a rate of two per minute. The parking-lot attendant processes incoming vehicles (collects parking fees) at a rate of four per minute throughout the day. Assuming D/D/1 queuing, determine total vehicle delay."

Answer:
(a) Work out put=692.83
(b) Change in specific entropy=0.0044
Explanation:
Properties of steam at 1 MPa and 200°C
We know that if we know only one property in side the dome then we will find the other property by using steam property table.
Given that dryness or quality of steam at the exit of turbine is 0.83 and temperature T=40°C.So from steam table we can find pressure corresponding to saturation temperature 40°C.
Properties of saturated steam at 40°C
So the enthalpy of steam at the exit of turbine
(a)
Work out put =
=2827.4-2134.57
Work out put =692.83
(b) Change in specific entropy
Change in specific entropy =0.0044
