Water will be pumped from a reservoir free surface of which is at an elevation of “z1” to reservoir the free water surface of which is at “z2”. Both of the reservoirs’ free surfaces at atmospheric pressures.Design a piping system that transmits water from the lower reservoir to the upper reservoir at a volumetric flow rate of Q (m3 /h).

Q = 200 (m3/h) Za = 10(m) Zb= 60 (m) Zc = 75 (m) L1=200 (m) L2=125 (m) "Pipe material is "Commercial Stainless Steel" "

1) Consider necesssary fittings( valves, elbows….)

2) Given data and cost elements, determine the optimum pipe diameter of the system . In order to do this:

3) Write the energy equation between z1 and z2 by taking the major losses associated with the pipe, minor losses associated with the fittings, sudden contraction, and expansion regions inside the system and the pump total head rise ”hp” into account .

4) The average velocity of the water inside your piping system should be between 0.1 and 5 m/s. 5) Calculate the head rise “hp” that must be provided by the pump.

6) Choose a pump that provides a head rise of ”hp” (that you calculated) near its most efficient working flow rate at your given flowrate Q from the local manufacturer’s catalogues.

7) Find the cost of the pipe per one meter (TL/m) and unit electricity price ( TL/kWh). Neglect cost of the pump or pumps.

(1) v₁ = 1.8

(2) 7150v₂+1350v₃  = 12780

(3) 7150v₂² + 1350v₃² = 23166

The pressure in a car tyre depends on the temperature of the in the tyre. When the air temperature is 27C, the gage pressure is 210 KPa. If the volume of the of the tyre is 0.025 m3, determine the pressure rise in the tyre when the air temperature rises to 57C. With the tyre temperature at 57C, determine the mass of air which must be bled off in order to decrease the pressure to its original value. Take the molar mass of air as 29g/mol.

PLEASE DO NOT SIMPLY REGURGITATE ANSWERS THAT ARE SIMILAR TO MY QUESTION. I Will report it as abuse.

Also, please be clear with your explanation:

A converging–diverging nozzle is designed to generate an exit Mach number of 2. The nozzle is supplied with air from a large reservoir in which the pressure is kept at 6.5 MPa. Assuming one-dimensional isentropic flow, find

a. The maximum back-pressure at which the nozzle will be choked

b. The range of back-pressures over which there will be a shock in the nozzle

c. The design back-pressure

d. The range of back-pressures over which there is supersonic flow on the nozzle exit plane

. A rectangular steel bar is subjected to a fluctuating load from 30 kN tension to 30 kN compression. The bar is 30 mm wide and 7 mm thick with a hole in the middle that is 4 mm in diameter. Find the fatigue and yield factor of safety if the steel is cold-drawn AISI 1040. If the fatigue factor nf<1 and ny>1 then that means that the system will fail at a finite number of cycles. If that is the case, estimate the number of cycles to failure.

A pump has a displacement volume of 8 in3. It delivers 20 gpm at 800 rpm and 1100 psi.

Air expands through a turbine operating at steady state. At the inlet, p₁ = 150 lbf/in.², T₁ = 1400°R, and at the exit, p₂ = 14.8 lbf/in.², T₂ = 900°R. The mass flow rate of air entering the turbine is 5 lb/s, and 65,000 Btu/h of energy is rejected by heat transfer.

Neglecting kinetic and potential energy effects, determine the power developed, in hp.
