A Carnot vapor power cycle operates with water as the working fluid. Saturated liquid enters the boiler at 1000 lbf/in.², and saturated vapor enters the turbine (state 1). The condenser pressure is 1.2 lbf/in.² The mass flow rate of steam is 1 x 106 lb/h. Data at key points in the cycle are provided in the accompanying table. State 1 2 3 4 p (lbf/in.²) 1000 1.2 1.2 1000 h (Btu/lb) 1192 783.4 416.3 542.5

Only question 1 please

Question 11) Roger gave the following account of a roller-coaster ride: 1 tried a brand-new ride at a science centre. There's a computer screen that tells you how much the car and the people in it weigh and how high and fast you travel. You get into the car and they strap you in. The car weighs 600 kg. At the top, it moves horizontally at a speed of 1 m/s. Then you drop 30 m, make a loop into the air and finish by riding over an 8-m hill. I don't remember our maximum speed or our speed at the top of the loop, but the ride was fantastic!" Answer the following questions without taking the force of friction into consideration. Show your calculations for each question. A v=1 m/s 20 m 8 m a) What is the highest speed Roger could have attained? What is the potential energy of the roller-coaster car when it is at the top of the b) loop? c) What is the kinetic energy of the car as it passes over the top of the 8 m hill? d) What is the total mechanical energy of the system?

2.2 Please help. Written on paper not typed on computer or keyboard please. Need help both questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

1.Impulse of a force is the integral of the force with respect to time over the time the force is applied. Impulse of a force is the integral of the force with respect to time over the time the force is applied. True False

Water flows through a horizontal pipe at a rate of 0.01 m /s. The pipe consists of two sections of diameters 5 cm and 2 cm with a smooth reducing section. The pressure difference between the two pipe sections is measured by a fluid manometer that has S=14.2. Neglecting the viscous effects, determine the differential height of fluid manometer h (m) between the two pipe sections. 5 сm 2 cm S
