pneumatic leverage refers to the ability of a pneumatic system to

1. Sketch the normal and tangential coordinates and the acceleration vector and on each airplane for each described motion on the path shown • Speeding up Slowing down • Slowing down Speeding up

solve a,b, c and d please. In a detergent-making process, 1400gal/h of water flows through a 2-inch pipe system as follows: Exit from pump, 2ft vertical, open gate valve, 14 ft vertical, 908 bend, 12ft horizontal, 1/4 open globe valve, 20ft horizontal, 908 bend, 6ft horizontal, 908 bend, 12ft vertical, 908 bend, 14ft horizontal, 908 bend, 4 ft vertical, 908 bend, 28ft horizontal, open gate valve, 3ft horizontal, entry to tank containing 30ft of liquid.  (a). If the pump and tank are both at grade level, estimate the head that the pump must deliver.  (b). If the pump inlet pressure is 25 psig, what is the outlet pressure?  (c). Estimate the pump shaft work ( d). If the pump is powered by an electric motor with 85% efficiency, what is the annual electricity consumption?

Suppose that you have designed a portable compressed-air supply system, as shown in the figure below,for filling scuba tanks and for driving pneumatics tools in garages and factories.The system consists of an electric motor, an air compressor, an air tank, a regulator and a pressure-reliefsafety valve.The regulator contains a pressure sensor connected to a power switch. The motor is switched on whenthe tank pressure drops bellow a fixed value and off at a slightly higher pressure. The pressure-reliefvalve is set to open at a higher pressure than the regulator motor off-pressure.Explosion of the tank is clearly a dangerous hazard. Three events are assumed to possibly lead to a tankexplosion:1. an internal tank defect such as poor welding2. an external cause such as a plant vehicle colliding with the tank3. Excess pressure in the tank. The excess pressure can occur only if both the control unit and thepressure-relief valve fail:The pressure sensor might fail to shut oof the motor because…

جية - A - Northern Technical University Technical Eng. College/Kirkuk Fuel and Energy Eng. Tech. Dep. 4th Year Students Final Examination (2022-2023) Subj.: Process of unit operation Date: 6/6/2023 Time: 3 Hours: Morning & Evening Study Note/Answer only four questions, including the first question Q.1: Water is to be cooled in a packed tower from 330 to 295 K by means of air flowing counter currently. The liquid flows at the rate of 275 cm³/m² s and the air at 0.7 m³/m² s. The entering air has a temperature of 295 K and a humidity of 20%. Calculate the required height of tower and the condition of the air leaving at the top. The whole of the resistance to heat and mass transfer can be considered as being within the gas phase and the product of the mass transfer coefficient and the transfer surface per unit volume of column (ha) may be taken as 0.2 s¹. Assuming, the latent heat of water at 273 K = 2495 kJ/kg, specific heat capacity of dry air = 1.003 kJ/kg K, specific heat capacity of…

What is the required diameter in meters of a cylindrical tank which has a length of 3 meters used for oil storage that will supply the engine for 5 days having a fuel consumption of 60Kg/hour at 27 degrees API? Please Answer # 9. If you can answer # 10 it will be appreciated much and rated high. Thanks!

How will you differentiate the three flight control systems used in large aircraft? (Mechanical, Hydromechanical, and Fly-by-wire)

Industrial Main List at least three advantages that fluid power has over mechanical power.
