Toluene is pumped from a large tank to a delivery station at a rate of 0.004 m/s. The tank is at atmospheric pressure, and the pressure at the delivery station is 400 kPa abs. The pump station is 2.1 m above the liquid level in the tank, and the delivery station is 5.2 m above the toluene level in the tank. The diameter of the suction and discharge line is 0.04 m. The head loss in the suction line is 3.5 m toluene, while in the discharge line is 6.6 m. The density of toluene is 850 kg/m3, and its vapor pressure is 8,000 Pa. The NPSH is
