- An axial fan having a hub diameter of 0.4 m and a hub ratio of 0.5 delivers a flow rate of 5 m3/s at a rotational speed of 1800 rpm. If the chord length at mean radius is 0.12 m, determine the pressure change across the fan using this formulaarrow_forwardQn.2. A piezometer and a Pitot tube are tapped into a horizontal water pipe, as shown in the Figure I below to measure static and stagnation (static + dynamic) pressures. For the indicated water column heights, determine the velocity at the center of the pipe. Clearly state all asuumptions and illustrations. hy-12 cm h- 7 cm hy-3 cm Water Stagnation point Figure 1arrow_forwardPlease fastarrow_forward
- A pump 260mm suction pipe and a 150mm discharge pipe is used to deliver 58L/s of water. The suction gage reads 15.6 kPa vacuum and the discharge gage located 120 cm above the suction gage which reads 110 kPa gage. Determine: a. The total dynamic head (TDH) in meters b. The water power in kW c. The pump efficiency in % if the power supplied by the motor is 15hparrow_forwardA one-fifth scale model of a water turbine is tested in a laboratory at T = 20°C. The diameter of the model is 8.0 cm, its volume flow rate is 17.0 m3 /h, it spins at 1500 rpm, and it operates with a net head of 15.0 m. At its best efficiency point, it delivers 450 W of shaft power. Calculate the efficiency of the model turbine. What is the most likely kind of turbine being tested?arrow_forwardTwo pumps (Pump A and B) have performance curves which can be approximated by the following equations: H_A = 340- (1.2(Q^2)), in feet H_B = 360 - (2.5(Q^2)), in feet where Q is in ft^3/s. If pumps A and B were to operate in parallel as depicted in the figure below, at what head (in ft.) should either pump be operated? ... Pump A Round your answer to 2 decimal places.
