All I can find so far is this:
Assuming a male of 6ft 600lb- approximately 22L of blood. 175lb- approximately 8.5L of blood.
Females would have less blood than males.
This was calculated using Nadler's Formula:
For Males = 0.3669 * Ht in metres^3 + 0.03219 * Wt in kgs + 0.6041 For Females = 0.3561 * Ht in metres^3 + 0.03308 x Wt in kgs + 0.1833
