Q.5 A pump circulates water through a closed pipe network connecting a water heater and a heating coil (heat exchanger) in a room. The total length of the pipe is 28 m and the diameter is 32 mm. There are six 90°-elbows and a globe valve in the network. The head loss through the water heater and the heating coil are 1.6 m and 1.2 m respectively. The water flow rate is 0.88 Ls!. The system uses schedule-40 steel pipes with threaded fittings. Calculate the (i) flow velocity and the unit pressure loss in the pipe. (ii) increase in head across the pump. (iii) power input to the pump if the efficiency of the pump is 70%.
! Required Information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Several forces are acting on a bolt as shown in the diagram below. It is desired to determine the resultant of all of the forces acting on the bolt. The axis of the bolt is at a 45° angle with respect to the x-axis. The line of action of force Pis parallel to the x-axis. The magnitudes of the forces and the angles labeled are as follows: P=38 N S= 64 N T=31 N a=15° B= 65° Q=52 N 8= 25° T S After performing a visual examination of the problem, what assumptions can be made regarding the four given forces? Check all that apply.
An acceptance test was conducted on a centrifugal pump having a suction pipe 25.4 cm in diameter and a discharge pipe 12.7 cm in diameter. Flow was 186 m³/hr of clear cold water. Pressure at suction was 114.3 mmHg vac and discharge pressure was 107 kPag at a point 91 cm above the point where the suction pressure was measured. Input to the pump was 15 hp. a. Determine the pump efficiency b. If the pump runs at 1750 rpm, what net flow, head, and brake hp would be developed and required if the pump speed were increased to 3500 rpm? Assume constant efficiency.
Apply the formulas in designing a hydraulic turbine to select the appropriate type of turbine for the following design considerations:a. Gross head = 200mb. Flow rate = 10m3/s c. Penstock friction losses = 10% of gross headd. Overall Efficiency = 95%e. Coefficient of velocity, Cv = 0.95f. Peripheral coefficient, Φ = 0.46g. Rotational speed = 3200 rpmCompute Ns and net head to validate the answer. Calculate also the diameter of the turbine wheel.
