A closed tank contains liquified butane gas whose specific gravity is 0.60. The tank pressure is 1.7 Mpa gage which is also the equilibrium vapor pressure of butane at the pumping temperature. Suction lines losses is 1.5m of gas and the static elevation gain is 4m. What is the NET POSITIVE SUCTION HEAD AVAILABLE?(NPSHa)

P-4 fuel (SG = 0.77) flows rough the Venturi meter hown in the figure below with a velocity Vo= 14.8 ft/s in the d1=6.00-in. pipe. In viscous effects are negligible, determine the elevation, h, of the fuel in the open tube connected to the throat of the Venturi meter. Assume h1= 7.70 in., h2= 5.70 ft, d2= 4.00 in.

An ion exchanger treats 1 MLD of water using an exchanger of capacity 100 kg/day/m3 with rate of flow being 0.5 m3/min/m2. Choose the correct statements assuming total hardness of water equal to 84 mg/1 as Cao. Total hardness of water is equal to 150 mg/l as CaCO3. Correct Option B Sodium Alumino - Silicates may be used as ion-exchanger. Correct Option lon exchanger can result in removing complete hardness. Correct Option Correct Option The height of ion exchanger required is 1.08 m if hardness of water is taken as 150 mg/1 as CacO3.

The allowable Net Positive Sustion Head (NPSH) for a pump provided by the manufacturer for a flow of 0.05 m³/s is 3.3 m. The temperature of water is 30° C (vapour pressure head absolute = 0.44 m), atmosphere pressure is 100 kPa absolute and the head loss from the reservoir to pump is 0.3 N-m/N. Find the maximum height of the pump above the sustion reservoir.
