1. A nozzle in a high-pressure liquid water sprayer has an area of 0.5 cm2. It receives water at 350 kPa, 20?C and the exit pressure is 100 kPa. Neglect the inlet kinetic energy and assume a nozzle isentropic efficiency of 85%. Find the ideal nozzle exit velocity and the actual nozzle mass flow rate.
2. Air flows into an insulated nozzle at 1 MPa, 1200 K with 15 m/s and a mass flow rate of 2 kg/s. It expands to 650 kPa, and the exit temperature is 1100 K. Find the exit velocity and the nozzle efficiency.
two forces applied as shown to a hook support. knowing that the magnitude of P is 35 N, determine by trigonometry the required angle if the resultant R of the two forces applied to the support is to be horizontal and the corresponding magnitude of..
Reconsider Prob. 14-46. Determine the required properties using EES (or other) software instead of the psychrometric chart. What would the property values be at a location at 3000 m altitude?
An A36 structural steel (36 Ksi yield strength) W8 x 40 member has been physically cut to 20 ft. long. This member is to be installed as a vertical column that supports a centric, axial compressive design load of 160,000 lb? and can be modeled as ..
You are a construction engineer working on a large concrete foundation project, involving the placement of over 500,000 c.y of concrete. The construction site is adjacent to a salt-water source (bay) & it is decided to set up a concrete batch plan..
Discuss the role of each physical, chemical and biological unit operations and processes employed in the wastewater treatment facility. If this treatment facility is required to supply class A recycle water to those industries for non-potable use
a 15 kg mass attached to a cord that is wrapped around a pulley and released from rest. the pulley has mass of 5 kg but is frictionless. consider the cord as mass less, inelastic and frictionless.
Find the modal frequencies and mode shapes for the frame assuming the columns are fixed at the top and the bottom and Sketch out the first and third mode shape.
Three reservoirs are connected by three pipes as shown in Figure 1 with hA = 100 ft, hB = 20 ft, hC = 0 ft, l1 = 1000 ft, l2 = 500 ft, l3 = 400 ft and D1 = D2 = D3 = 1 ft. Determine flow rate into or out of each reservoir if friction in each pipe is ..
A barge measures 10 ft (depth) by 35 ft by 120 ft and weighs 100 U.S. tons. The barge floats in fresh water (specific weight = 62.4 lb/ft3) and is evenly filled with 38,000 bushels of corn (60 lb/bushel).
A beam is simply supported at the ends and is continuous over two spans. The left-hand span is 16 ft and the right-hand span is 20 ft. The beam supports a uniform load of 900 plf, which includes its own weight,
an increment of vertical stress of 150kpa compress the sample to a void ratio of1.43. what is the over consolidation ratio of the soil at the unloaded condition.
