If 750 compacted cubic yards (ccy) of in-place soil is required for a project, how many loads of import will be required? The import material has a swell of 30 percent and shrinkage of 90 percent. The trucks can haul 10 loose cubic yards.
What will be an ideal response?
Determine the volume of the haul and the number of loads as follows:
Required bcy = 750 ccy / 0.90 = 833 bcy
Loose cubic yards = 833 bcy (1 + 0.30) = 1,083 lcy
Loads = 1,083 lcy / 10 lcy per load = 109 loads

An insulated steam turbine produces 25.0 MW of power. Steam enters the turbine at 10.0 MPa, 500°C, and with a velocity of 150 m/s, through a duct with a cross-sectional area of 0.01 m2. The steam exits with a velocity of 10 m/s, at a pressure of 100 kPa. Determine the exit temperature and, if applicable, the exit quality of the steam.
Given: P1 = 10.0 MPa; T1 = 500°C; V1 = 150 m/s; A1 = 0.01 m2; P2 = 100 kPa; V2 = 10 m/s; W?=25.0 MW=25,000 kW; Steam Assume: Q? = 0 (insulated) Also, for a turbine, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?PE = 0 What will be an ideal response?
