a 3200-lb car (Cd = 0.35, Af = 25ft^2, and p= 0.002378 slugs/ft^3) has 14-inch-radius wheels, a drivetrain efficiency of 93%, an overall gear reducation ratio of 3.2 to 1, and drive axle slippage of 3.5%. the engine develops a maximum torque of 210ft-lb at 3600 rev/min. what is the maximum grade this vehicle could ascend, on a paved surface, while the engine is developing maximum torque? (assume that the available tractive effort is the engine-generated tractive effort.)
A reverse osmosis plant desalinates 5X10^6 L/day of feedwater containing 1500 mg/L of salts, yielding 3X10^6 L/day of product water with 75 mg?l of salt. What would the salt concentration be in the brine?
Assume you are observing traffic in a single lane of a highway at a specific location. you measure the average headway and average spacing of passing vehicles as 3 seconds and 150 ft, respectively. calculate the flow, average speed, and density of..
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/sec)
a regular hexagonal pyramid has an upper base edge of 16 ft. and a lower base edge of 28 ft. if the volume of the frustum is 18041 ft^3., find the lateral area of the frustum.
the pin at B is attached to member ABC and can slide freely along the slot cut in the fixed plate. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when.
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
