The north-south streets of a grid have block lengths of 250 m and the east-west streets have block lengths of 200 m. Desired speeds of progression are 45 km/h north-south and 35km/h east-west. Determine the appropriate alternate systems, cycle, and actual speeds of progression for two-way

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
