Question 1 A 1.2 m diameter circular tank is being fill

Question 1
A 1.2 m diameter circular tank is being filled with water as shown in Figure B-1(b). The velocity of flow of water from the pipe is 3 m/s. What will be the rate of rise (in m/s) of the water level in the tank?
Diameter 30 cm
Water Velocity = 3 m/s
1.2 m
Question 2
Calculate the diameter head loss and pressure drop for a laminar flow along a 20m pipe for fluid with kinematic viscosity of 1.15 x10-5 m2/s if velocity at center of pipe is 0.5m/s.
Question 3
A water pump with efficiency at 95% is supplied with 90kW electric power to provide a pump head of 100m. The impeller of pump rotating at 1800rpm has blade height of 5cm with inner and outer diameter being 4.8cm and 18cm respectively.
Calculate the following:
a) Linear velocity of outer blade
b) The flow rate
c) Outlet velocity
Question 4
Air flow in a diffuser has a density of 0.762 kg/m3 at rate of 0.7m3/s. Calculate the exit area if the density and velocity at exit is 2.21 kg/m3 and 30 m/s respectively
