1.Helium(15 degrees Celsius, 1atm) will be transported in a straight horizontal copper tube over a distance of 150 m at a rate of 0.1 m^3/s. If the pressure drop in the tube should exceed 6 in h20, what is the minimum pipe diameter? ( first classify the problem as case 1, 2 , or 3)
2.The electrical power supplied to the motor is 90 kW. The motor in turn delivers 100 hp at a speed of 1000 rpm to a hoist arrangement for an elevator. Define the electric motor as the system and calculate the rate of work for the system.
3.A low consumption solar refrigerator uses 12-v d.c. battery for the supply of 60 W of electrical power to the motor that drives the compressor of the refrigeration device. What is the current supplied to the motor?
4.A 45 W electric mixer is operated for 5 minutes while mixing a 2 kg shake. Assume Csubv=4200 J/kg-K for the liquid. Determine the temperature rise (in degrees C) of the milk shake.
Water at 20 Degree C is pumped at a constant rate of 9m^3/h from a large resevoir resting on the floor to the open top of a anexperimental absorption tower.
If the live load on a 30 foot long beam is 1.2 kip/feet and the dead load is 0.8 kip/feet determine the maximum moment in the beam (kip-ft) if it is pinned at both ends. Assume the weight of the steel is 0.3 kip/feet.
Discuss whether shoe A (leather) or shoe B (synthetic) is better for the environment based on the data in the table below. Is it possible to weight one aspect (air
The aerodynamic drag of a new sports car is to be predicted at a speed of 50mph at an air temperature of 25 degrees Celcius. Automotive engineers build a one-fifth scale model of the car to test in a wind tunnel.
A stream conveying a flood peak of 50 m3/s (velocity 1.25 m/s and depth 1 m) is divided into 1 km long reaches for solution of the unsteady equations. Determine the largest value of ft for which the solution will be stable.
38 mL of 0.02 N HCl is added to neutralize 50.0 mL of lime water (Ca(OH)2). Calculate the hardness of lime water as mg/L as CaCO3 and mg/L as Ca(OH)2.
Three particles are sliding along a flat, frictionless surface. mA = 0.4 kg, mB = 0.5 kg, and mC = 0.4 kg. Before any collisions take place, vA = 15i m/s, vB = 10im/s, and vC = 5 m/s. e = 0.85 between A and B and e = 0.6 between B and C.
A pond is used to treat a dilute municipal waste-water before the liquid is discharged into a river. The inflow to the pond has a flow rate of Q = 4,000 m3/day and a BOD concentration of Cin = 25 mg/L.
you are designing a highway to AASHTO guidelines on rolling terrain where the design speed will be 65 mi/hr. At one section, a +1.25% grade and a -2.25% grade must be connected with and equal tangent vertical curve.
A cylinder with a 6.0 in., diameter 12.0 in. height is put under a compresive load of 150 kips. The modulus of elasticity for this specimen is 8000 ksi and Poisson's ratio is 0.35. calculate the final length and the final diameter of this specuman..
The rigid bar AD is supported by two steel wires of (1/16)" diameter (E=29x10^6 psi) and a pin and bracket at D. Knowing that the wires were initially taut, determine (a) the additional tension in each wire when a 120-lb load P is applied at B
