| The design peak flow of the hotel water supply system shall be calculated based on the number of plumbing fixture water supply fixture units. When the probability method is adopted, the design peak flow formula is: qg = 0.2 × U × Ng, where U is the simultaneous flow probability of plumbing fixture water supply fixture units, and Ng is the total number of plumbing fixture water supply fixture units for the calculated pipe section. Water supply fixture units for hotel guest room bathrooms: shower 0.75, washbasin 0.50, toilet 0.50.
