The interstate highway system carries nearly 60,000 daily person miles per route mile, 26 times as many person miles per route mile as all other roads (including low usage rural roads), and 22 times as many person miles per route mile as intercity rail (Amtrak) and urban rail combined.
The expected urine output for an adult is 0.5ml/kg/hr. This roughly equates to 30-40ml per hour in an average sized adult.
The normal range for an adult urinary output is between 400 to 2,000 mL of urine daily -- with a normal fluid intake of about 2 liters per day.Values for normal urinary output may vary slightly between laboratories. A urine output of 500 mL per day is generally considered adequate for normal function.Factors other than kidney disease that can influence how much you urinate in a day include how much water you consume, the amount of fluid lost in perspiration, your caffeine and alcohol intake and any medications you've taken. urine output of 500 mL per day is generally considered adequate for normal function.
