At a cruise ship terminal, each day on average 1000 passengers embark on ships. On average, passengers spend 5 days on their cruise before returning to this terminal. If the flow unit is a passenger, then what are the flow rate and flow time of this process?

The flow rate is 200 passengers per day and flow time is 5 days.

Explanation:

Average passengers that embark on daily cruise = 1000

Number of days spent before they return to the ship terminal = 5 days

Flow rate of passengers can be defined as the number of passengers that pass per unit time.

Mass flow rate = flow unit/ unit time

Flow unit = 1000 passengers

flow time = 5 days

Mass flow rate = flow unit/ flow time

Mass flow rate = 1000/5

Mass flow rate = 200 passengers per day

The flow rate is 200 passengers per day and flow time is 5 days.

Flow rate in passengers/day = 200 passengers/day

In passengers/s = 0.0023 passengers/s

Flow time in days = 5 days

In seconds = 432000 s.

Explanation:

The flow unit is in passenger while the flow rate will be in passenger per unit time.

Flow time is the time taken for the passenger to spend on their cruise before returning.

Given:

Number of passengers = 1000 passengers

t = 5 days

Converting 5 days to secs,

5 * 24 hours * 3600 s

= 432000 s.

Flow rate = number of passengers/flow time

= 1000/5

= 200 passengers/day.

OR

= 1000/432000

= 0.0023 passengers/s
